Objective: Designing machines, vehicles, and structures that are safe, reliable,and economical requires both efficient use of materials and

assurance that structural failure will not occur. This courseconsiders the role of material selection in the design of mechanical

and structural elements with respect to static failure, elastic

stability, residual stresses, stress concentrations, impact, fatigue,creep, and environmental conditions on the mechanical behavior ofengineering materials (metals, polymers, ceramics, composites).

The professional and ethical responsibility of the engineer in thiscontext will be considered where appropriate.

Ultrastructural and microstructural aspects of materials are

reviewed in terms of how they influence mechanical properties.Mechanical test methods are reviewed. Models for deformation

behavior of isotropic and anisotropic materials are considered.Methods to analyze static and fatigue fracture properties are

considered. Rational approaches to materials selection for new andexisting designs of structures are examined. Failure analysis

methods of failed structures are considered. Failure analysisexamples of actual failed structures will be discussed and the

professional and ethical responsibility of the engineer will beconsidered.

Laboratories: There will be 4 mandatory laboratories. Times and locations will

be arranged as everyone will have to do the lab at the same time.Each laboratory will require at least 1 hour of preparation prior to

the lab meeting to organize procedures and expected results. FORSAFETY REASONS, STUDENT ARRIVING AT THE

LABORATORY TIME UNPREPARED OR WEARING

INAPPROPRIATE CLOTHING WILL NOT BE ALLOWED

TO OPERATE EQUIPMENT AND MAY BE DENIED

ENTRANCE TO THE LABORATORY. A report will be part

of each lab. Group Lab reports will be prepared, with differentgroup leads assigned for each lab.

Homework: Homework problems are to be worked on individually, unless

otherwise specified. Homework assignments will be givenapproximately once a week. Homework is due on the date shown

by 5PM. BECAUSE OF THE SHORT SUMMER TERM, NOLATE HOMEWORK WILL BE ACCEPTED.

Assessment: The homework assignments will be utilized to assess the students

ability to apply their knowledge of mathematics, science andengineering to solve formulate and solve problems. The

homework assignments will also be utilized to assess the studentsability to consider materials selection in the design components or

systems to meet a specific design rationale. The Laboratoryreports will be utilized to assess the students ability to design and

conduct experiments and to analyze and interpret data. LaboratoryReports will be utilized to assess the students ability to

communicate effectively in written format. The Exams will beused to assess the students ability to synthesize and appropriately

apply the concepts concerning materials selection and deformation,fracture and fatigue of materials learned in class.
