 Dear All
I has question about these stresses.
1.Are deviatoric stress generate plastic deformation?
2. Are hydrostatic stress generate plastic deformation?
3.What is the advantage of transferring strain tenser orientation to the principle coordinate axes? 
4. What is the difference between rupture and fracture stress?

Particle size and debonding stress

Hi everybody,

do you know where I can find some informations about the relation

between particle size and critical normal stress at the interface particle /matrix

for a particle embedded in a matrix?

I read the Chen's article 'Size effect of particles on the damage dissipation in nanocomposites'

but this article deals with spherical particles. I am studying clay/matrix nanocomposites and I would like to

calculate the relation between clay size and debonding stress.

hi, there!

I have read a "Manual for LS-DYNA Wood Material Model 143"(website: http://www.tfhrc.gov/safety/pubs/04097/sec150.htm#toc_1_5_1 and http://www.tfhrc.gov/safety/pubs/04097/append_e.htm).

I have two question:

Mini-Symposium on Electro-Active Materials at WCCM IX

Dear Colleagues,



We like to draw your attention to the mini-symposium



MS6043 - Computational Mechanics of Electro-Active Materials



organized by Prof. Ellen Kuhl, Prof. Andreas Menzel and myself in the

WCCM IX. The abstract outlining the objectives of this integrative

mini-symposium is enclosed to this post as plain text and also as a

pdf-attachment.
