Description of Funded Research Projects

NPRP # 7-032-2-016 Fluid-Structure Interaction of Elastic Shells for Aerospace and Biomedical Applications, Sponsor

Qatar National Research Fund, Collaborative Institutions: McGill University, Canada (Mech. Eng.), Texas A&M University

TX, (Aero. Eng), Weill Cornell Medical College at Qatar (Medicine), 03/01/2015-06/30/2018 $ 857,767.75 (completed)

Description: Shells are light-weight structures made of shell elements, typically curved, and assembled to form large

structures such as aircraft fuselage, spacecraft, rockets, cars, and storage tanks. Shell structures also appear in the form of

membranes in many biological systems such as arteries, the pulmonary passage and veins. In these applications, the

structures have a thickness small compared to the other dimensions and are referred as thin-shells. In addition, they undergo

large displacements and must be analyzed using nonlinear elasticity. Secondly, because the shells are subjected to an external

loading in the form of a fluid flow (i.e. air for aerospace applications and blood for medical applications), it is necessary,

yet not trivial to account for the interaction of the fluid on the structure to fully describe the dynamic behavior of the shells.

This program of research will built on existing theoretical models and will improve the treatment of nonlinear vibrations and

dynamic stability of shells by i) allowing higher-order shear deformation, rotary inertia and thickness variation and, (ii) by

including hyperelasticity and viscoelasticity as material nonlinearities. In particular, we will focus on two problems: i) the

development of an energy-efficient, safe shell-element made of advanced materials (composite, sandwich and/or functionally

graded materials FGM) for aerospace, and oil and gas industries and ii) the study of a biomechanics problem known as

aortic dissection in which a tear in the inner wall of the aorta causes blood to flow resulting in a catastrophic failure. Both

problems will require a numerical and an experimental phase. Numerical codes will use existing lower-order models as a

base and experimental procedures will include sophisticated apparatus such as a Laser Doppler Vibrometer (LDV) placed

in water tunnel as well as wind tunnel facilities. We will also enlist surgeons and other medical professionals to fully

understand the mechanics of dissection and the numerical analysis will predict the risks of rupture due to geometric

imperfections of organs. Other important biomedical applications for the design of shape-memory-alloy (SMA) shells with

fluid interaction are implantable medical device such stents, valves and filters. The program specifically addresses two of

Qatar’s research pillars in the area of i) Energy and Environment and ii) Health. This program will open up ways for Qatar

to be at the forefront of research in nonlinear analysis of shell structures while collaborating with international centers for

the development of new, safe and reliable materials.

TEES (Transformative Educational Experience) Peer-Mentoring Program for Female Engineering Students at Texas

A&M University at Qatar, Sponsor Texas A&M University at Qatar, Oct 2017-June 2018 ~ $50, 000 (completed)

Description: Despite the enormous progress made over the last fifteen years, our female graduates report entering a

workplace that is isolating and hostile, leaving success stories to remain scarce. Lack of role models and rooted gender-bias

are being seen by our female graduates as detrimental to opportunities to advance in the workplace. We seek funding to support activities related to the establishment of a peer-mentoring program. The program will match

female freshmen with upper class female students. The senior students will serve as a support to incoming students for their

new university life, easing the transition from high school, informing them on academic and research opportunities, guiding

them on how to approach faculty and/or educating them on the resources available at TAMUQ (such as the library, Academic

Success Center, Counselling, Student Societies etc.). Tasks associated with this program will include: recruitment of mentors

and mentees (online survey, missions and goals statement), screening applications, mentor and mentees training

(expectations from each), matching phase (age, major, ethnicity, personality) and program evaluation (length and frequency

of meetings, outcomes etc.). In addition to design and development, benefits for the students will encompass communication

and time management skills, networking, and community engagement.

NPRP 5-353-2-138 Surgical Threads Simulations Based on a Novel Information-Theory Approach- Sponsor: Qatar

National Research Fund, Collaborative Institutions: Texas A&M University, TX (Mech. Eng. & Elec Eng.), Weill Cornell

Medical College at Qatar (Medicine), Chalmers University of Technology, Sweden (Eng. & Comp. Science), 10/2012-

12/2015, $1,032,559.46 (completed)

Description: Texas A&M University at Qatar in partnership with surgeons from Cornell Weill Medical School at Qatar is

proposing a research program aimed at creating a physics-based software that will predict the deformation of surgical

threads when subjected to conditions commonly encountered during surgery. Of particular interest is be the study of thread

tangling, a non-linear and dynamical process detrimental to surgeons during knot formation. The software will use the

Cosserat theory of elasticity, a theory particularly suited to describe long and thin flexible structures (rods) just as those of

http://en.wikipedia.org/wiki/List_of_structural_elements

http://en.wikipedia.org/wiki/Aorta


surgical threads which take spiral-type configurations in addition to bend and twist. The uniqueness of the proposed work is

that it will based on a novel discrete optimization-based dynamic programming technique originally developed for

information theoretic problems related to text strings and which will have the potential to reduce the computing time. We

also plan an experimental phase on bending and twisting deformations of threads to validate the data with the simulations.

The proposed research is interdisciplinary in nature with experts drawn from mechanical and electrical engineering,

computer graphics and the medicine. The outcomes of this research will help fill the gap in the area of medical simulations

which lag far behind simulations in other fields. The software will train a new generation of medical school students and will

have the potential to diversify Qatar’s economy.

NPRP 5-129-4-559 Multiscale Investigation of the Relationship between the Microstructure and Deformability for

New Generation Ultra High Strength Multi-Phase Steels for Automotive Applications- Sponsor: Qatar National

Research Funds, Collaborative Institution: Washington State University 1/2013-6/2016, $1,016,997.46- completed

Description: The ever increasing cost of energy coupled with environmental concerns, have lead the automotive industry to

consider various energy saving measures. Among them, reduction of the vehicle weight is one of the most effective, provided

that stringent safety regulations are maintained. Accordingly, the industry world-wide has been adopting various types of

advanced high strength steels (AHSS) which, when properly designed, can have both high strength and ductility. AHSS

achieve their strength by a combination of factors: grain refinement, solid solution strengthening and precipitation hardening

(PH), transformation strengthening and grain boundary strengthening. Although recent advances have demonstrated the

feasibility of using AHSS, there is a lack of fundamental understanding of the driving mechanisms for ductility/formability,

strength and fracture/crash-worthiness and how they relate to the underlying microstructure, as well as lack of material

models that relate properties to the microstructure. The objectives of this proposed work are: 1) to investigate AHSS steel

(with emphasis on DP and PH) by an integrated multiscale experimental and modeling approach to understand the local

deformation mechanisms, 2) to identify the appropriate mechanical and microstructural properties that have significant

influence on the local deformations and 3) to develop fundamental understandings on key mechanical properties and

microstructure features influencing the local formability.

What Do Drillstrings and Surgical Threads Have in Common? Sponsor: Qatar Foundation Research Division, “Best

Research Program of the Year: Category Computing” awarded Dec. 2010- $100,000.00- (completed)

Description: Drillstrings used in oil and gas operations are long circular columns approximately 3 to 5 km long, 30 to 50

cm in diameter while surgical threads are typically 75 cm to 1 m long and 0.5 to 1 mm thick depending on the type of surgery,

so both share the characteristic of having a diameter to length ratio on the order of 10-3. Drillstring operators need to

constantly monitor the position of the drilling apparatus as excessive vibrations can lead to sudden equipment failure.

Likewise, a surgeon would want to avoid thread tangling, a non-linear and dynamical process particularly detrimental during

knot formation. The elementary Euler-Bernoulli or even the Timoshenko beam theory is insufficient to predict the correct

configuration of these structures which will coil, i.e. twist around their own axis in addition to bend and twist. Instead we

will use finite element computational tools using the less known Cosserat theory of rods. In the case of surgical thread, the

goal of our research program is the development of a software that will be used by medical school students to practice the

task of surgical suturing so the program’s immediate benefits are pedagogical and also in line with the Qatar Sidra project

to offer state of the art medical training. In the case of drillstrings dynamics, the objective of our program is to understand

the interactions between the vibration sources and drillstring-BHA responses and to offer “real time” assistance to drilling

rig operators by developing an advanced dynamics simulation software (ADDSS). With such high associated operational

costs, the anticipated benefits of the program are clearly economical. By engaging simultaneously in these two research

programs, we hope to demonstrate that the Cosserat rod theory is a powerful tool that can be used to solve a wide range of

applications that may appear very distant otherwise.

or anomalies beyond those who could traditionally be displayed on a flat screen.

Award # 0844082 International Institute for Multifunctional Materials for Energy Conversion (IIMEC), Sponsor:

National Science Foundation, Director: D. C. Lagoudas, TAMU, Aero. Eng., (A. Ruimi, International Collaborator),

Description: Texas A&M University, in partnership with Georgia Institute of Technology, the University of Houston and

international research collaborators at universities in North Africa, the Middle East and Mediterranean countries propose

to establish an International Materials Institute focusing on transformative research in multifunctional materials exhibiting

strong coupling among different fields, resulting in various forms of energy conversion. The rationale for the International

Institute for Multifunctional Materials for Energy Conversion (IIMEC) is that Middle-Eastern and Mediterranean countries

are of increasing importance for the global economy, confluence of cultures, and vital for international stability. The

materials scientific challenges of importance to these countries are similar to the US, mostly related to energy conversion,

storage, transmission and transportation. IIMEC’s geographical focus on North Africa, the Middle East and the

Mediterranean will bring this region into the Materials World Network. The participant countries are poised to contribute

to the international research enterprise: they have under-utilized human resources and a strong upcoming young population;

there are well-trained scientific communities and advanced research facilities scattered throughout the region; and many of

their researchers have strong theoretical and computational backgrounds. Combining this expertise and human resources

with the multidisciplinary research experience of the US participants, excellent experimental materials facilities at Texas

A&M and Georgia Tech, and well-planned guidance in research will result in enhanced connections between the US and this

region.
