Hello,
I have a simple problem but I am having a mental block concerning combining three different materials with different poisson's ratio and modulus. The problem is a plate with a hole and I can generate a mesh and apply load but I can not seem to create three materials and combine them together. Any help would be greatly appreciated. Here is what my input file looks like:
/Title, Isotropic Plate w/ a hole and mesh refinement

*Set, r, 100e-6
*Set, p, 15e6
*Set, E1, 12e9
*Set, E2, 15e9
*Set, E3, 6e9
*Set, PRXY1, .27
*Set, PRXY2, .3
*Set, PRXY3, .29

Changing attributes to areas
I have only one area with it's constituent properties mapped onto the other areas. They must be glued together but I need them to have different properties. Any help would be greatly appreciated. Thank you for your time.
