Dear Collegue



We are organising in July 7-9, 2010 an Euromech workshop on Multiscale

effects in Fatigue, at the Ecole Polytechnique, near Paris in France.

Outcomes and topics are detailed on the following web site:

We would be honoured if you could contribute to this workshop to present

some of your recent research results.  The workshop is thought as a small

Recent experiments have shown that a voltage can induce a large deformation in an elastomer of interpenetrating networks. We describe a model of interpenetrating networks of long and short chains. As the voltage ramps up, the elastomer may undergo a snap-through instability. The network with long chains fills the space and keeps elastomer compliant at small to modest deformation. The network with short chains acts as a safety net that restrains the elastomer from thinning down excessively, averting electrical breakdown.  It appears possible to find a dielectric elastomer capable of giant deformation of actuation.  You can read the paper, or take a look at the slides posted here.

Dear all

I want to start modeling the Hyper foam behavior in abaqus software, it is very usefull for me to consult with someone who works on that.

Dear all,

I' m trying to make a model in VUMAT for shape memory alloy based on Lagoudas 's thermomechanical constitutive model. It seems that It's necessary an iteration to evaluate the thermoelastic prediction.

My questions are : is it possible to use an iterative loop in the VUMAT or it's better to avoid it??Could someone suggest me a different way so that I can avoid the iterative loop?

Many thanks,

Cece

Dear Collogues,

This paper presents a geometric theory of the mechanics of growing bodies.



This paper is dedicated to the memory of Professor Jim Knowles.
