Topology optimization
Dear members,
I need some suggestions about review articles on "Topology optimization of inelastic materials". If some one have it please forward it to me.
Thanks in advance.

Damage modeling in ABAQUS 6.9 in surface based cohesive behavior
I am working on shear failure of sandwich composites.I have modelled a sandwich composite with surface based cohesive behavior in ABAQUS 6.9.Now i have to do damage modelling. For damage initiation i have to describe values of 'peak values of contact stress' or 'peak values of contact separation'.In addn i also have to describe values of 'critical fracture energy' for damage evolution. I don't know how to find these values or where from i will get these values.
My initial experience with VTK
I wrote my first experience of using VTK with my hp-FEM code here. This is only with linear tetrahedra. To use VTK for high-order elements seem formidable, altough there's a paper that describes how it can be done. If anyone has experiences with VTK in FEM, I'd love to consult with you.

Composite
Hi,
My Name is Moiz. I need some material about composite parts fabrication and the details about how the ply geometry is decided based on strength requirements. Any help would be really appreciated.
Thanks,
Moiz
Dielectric elastomers of interpenetrating networks
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.

Hi
When I was going through few research articles related to earthquake analysis, they say: A compuetr code was developed where in which the eartquake input will be in either accelerogram or a displacement time history, digitized in in the appropriate format. What does it mean? Doest it mean that in studying simulation of seismic analysis we need to load that code as input? How to get an idea about that codes? Where to get? How to use?
Please help.........
Thanks in advance........

I am fairly new to ANSYS and have been trying to model the interaction between glass micro-spheres and silicone polymer micro-structures for my dissertation research. I've been working through the online manual, but have been getting very odd results when running the simulation. Any help at all would be appreciated. The summary of my problem is as follows:
