Crystal Mechanics


How would I model the shear stress slip and direction in a crystal? In other words, if I have all the necessary material information how can I use the 3D structural mechanics module in Comsol to figure that out.

Thank you

Re: Crystal Mechanics

Hi

well for me that means selecting "anisotropic material properties" and play with the full tensors, and extensively with the coordinate systems.

I beleive you need the structural or the mems module to take full benefit of this

One thing, check carefully the numbering of the indexes, as there are many norms, and COMSOL uses different coordinates for standard material and for PZT material, following the main definition commonly used. This is well described in the doc, but very easy to forget while programming

Good luck
Ivar
