State-of-the-art understanding of cracking for porous materials?

Submitted by Al Zappor on

It seems there are quite a few experimental studies [1,2] on the fracture properties of porous materials, like nanoporous low-k dielectrics, as a function of porosity. Can anyone point out some references on the theoretical part, like the available models, computational methods or analytical approaches that can capture microstructure information, including porosity, pore geometry etc. Interface delamination of porous materials is also of interest. Thanks.

Crystal Plasticity

Submitted by hamanh on

Dear Mechanicians,

 Recently I have seen many researches on the crystal plasticity, Could someone tell me some basic difference between classic plasticity and crystal plasticity ?! and what is the crystal plasticity theory for ? 

 

Thank you very much

Best Regards
