Summary



ABAQUS Scope

Perform meaningful linear and nonlinear

analysis.

Typical cases:

This world is non-linear.

o Large motion of an elastic-plastic pipe hitting a rigid wall;

o Inelastic buckling collapse of a thin-walled elbow

o Explosive loading of an elastic, viscoplastic thin ring

o Consolidation under a footingo Buckling of a composite shell with a hole

o Deep drawing of a metal sheet

o ……

Part

Individual part can be duplicated and thenmodify to form new part.

modeling object

Assembly

Module name

Operate:

1. Extrude

2. Revolve

3. Sweep

Assembly

1. Individual part: Translate, rotate

2. Two part: Face to face, coaxial,

edge to edge, ….

Note: Different parts inassembly have NOinteraction even they arephysically contacted.



Workout Example

100 cube with a 50 radius 1/8 ball

How to draw this in AutoCAD or SolidWorks?We draw with ABAQUS/CAE



Sketch Part I



Sketch Part I --- cont’d

Need: Extrude from the Top



Select Plane for Part II

Easy !!!



Interaction --- Parts Relations

Interaction is to tell ABAQUS about how the parts and partsinteract and self-interact.



Workout Example

In contact, many times it is hard to choose the contact plane from theassembled part. Define the surfaces in the assembly by showingone part at a time.

Part

Assembled with two parts

Want these two parts tied together by two planes in the middle.

Define Interactions --- Summary

Since ABAQUS only checks the nodes of theslave planes, we selected the planes with large

deformation as slave planes. From material point of view, we usually choose

soft material (finer meshing) as slave planes(regions).

Same material does not matter.

Meshing --- Partition to Form Simple Part

How Simple is called Simple?

Color is Green. Color Orange --- Too Complex.

Meshing Steps



Meshing Steps

Try to turn everything into green by cutting parts (virtually because

they are still connected and cutting is just for meshing).

Summary

ABAQUS is user-friendly and easy.

ABAQUS HOWTO: learn two examples inAppendixes B and C of book “GettingStarted with ABAQUS”.

Hope all of us start to rock-and-roll withABAQUS.
