Question

Briefly answer

1). In an FE simulation with Abaqus, if the unit for the length is μm and the unit for the force is Netwon, what is the correct unit for the elastic modulus? Why?

4). Write down the global matrix equilibrium equation for a static FE analysis of a structure.

5). What is integration point? Where can we obtain the most accurate stress results within an element from an FE analysis?

6). What is a plane stress problem? Provide an Abaqus element code for a plane stress element.

7). What is an axisymmetric problem? Provide an Abaqus element code for an axisymmetric element.
