Multiple pieces, same material - differing orientations
Posted: 16 May 2017, 03:36
I want to use Elmer to study thermally induced stresses in grains of Cu (say).
I think I have the rotation of the anisotropic elasticity matrix working, thanks in large part to previous forum posts.
I edited the Cu entry that came with the Elmer package (in egmaterials.xml), in order to introduce the anisotropic elasticity matrix. But . . .
I have also "had to" edit egmaterials.xml - to add several varieties/names of Cu. Otherwise, one version/entry is spread to all bodies with the same name. This can make sense, but not if I want to use Cu (say) and have the same material - but with different orientations.
In short: Is adding multiple entries for the "same material" the only approach?
Thanks,
Tim
