In the one-dimensional example above we used a simple process based on equilibrium to
illustrate assembly. Now we cover two processes by which assembly may be

The figure shows a 3-rod, 2-shear panel assembly. Use finite element analysis methods to
compute the vertical displacement at node 1 and the shear stress in the shear panels. You
will need to make use of a computational code such
Solve the portal frame problem in the Kim text on page 406. This assignment will lead

A simple users manual for ABAQUS may be found in the folder ABAQUS manual for
Fish on elearning. You are to use ABAQUS to analyze the example of a hole in a

HW #4 Sp2011 AEM461
HW#3 was to compute the solution to Prob 2, Chapter 2, page 99 in Kim.
Repeat this solution but solve using MATLAB. See Appendix C in Kim.
You must attach your MATLAB code printout and the results printout.
