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.

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
I'm working on a MSc thesis involving both rigid body (zero energy) & deformational (elastic) modes and their orthogonality wrt mass matrix. I want to prove that elastic modes are mutually orthogonal (done !), that elastic & rigid body modes are so (sort of done !) & that rigid body modes also are so (unsure how ?). Can anyone offer any advice ?
Thanks, John.
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.
Hello to everybody,
Can somebody help me with advice in the next problem : I want to study an dynamic movement of some beams, with rigid body option from ANSYS Classic. I encountered the problem when I want to choose the element type for cilynder. I choose LINK11. But I need to simulate what is happend between the moment when is applied the force on cilynder and imposed lenght of ciclynder after pool.
How I can settup the properties of element LINK11 to satisfy my results.
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
Hi, i've got the following Problem:
I am running an Abaqus/Standard Analysis in which i am importing the results from a previous Explicit Analysis.
The thing is, I only want to Import the deformed mesh (displacement) and the damages to my model.
I tried using the "Predefined Field" option, but this imports every result from the previous analysis.
Is there any way I can choose which variables to import (e.g. U3,...) ???
Thanks for any help!
