Has anyone compared the results of Ansys solid5 element and Abaqus c3d8 element? I tried a very simple example with
exactly same conditions for both elements but got very different displacement results. I put both input files here,
can anyone help me check whether there is something wrong? Thanks.
Ansys Input:

Hi !!! all
I really struglling to get the JWL and Lee Traver EOS parameters for RDX .
If anybody can help seriously I will be highly obliged. Atlest the EOS
parameters of Comp-A5 or PBX 9604 having higher percentage of RDX (98.5
% and 96% respectively) will be sufficient.
Hi !!! all
I am doing the Hydrocode simulation using AUTODYN 2D Explicit Hydrodynamic Code. There is apoint of doubt in simulation of a 2D problem regarding the location of Detonation inside the explosive. In the case of a conical shaped charge it is very easy to assume the detonation at the apex of the cone but in case of FLSC being a linear cord and the initiation is done axially, it is very difficult to assume the same condition as that of conical shaped charge.
Please give me some useful solution.

A problem we are trying to solve in ABAQUS-6.9 involves user defined Fortran subroutine to be compiled by ABAQUS. The default compiler used by ABAQUS is ifort, but what we have is pgf90. Is it possible to make ABAQUS use pgf90 compiler instead of the default ifort ? How?
Thank you

In ANSYS Gives following Error......
Error...."Use of the M switch is no longer recommended for normal ANSYS use. ANSYS now dyanamically allocates memory as needed. Only use the -M switch if you are certain that you need to do so".and suddenly ANSYS window close automatically.....
please give the suggestions
Dielectric elastomer can undergo giant deformation, but are susceptive to various failure modes. i.e electrical breakdown.
Some experimental papers (Kofod, Plante, Chen, see the attachment) reported the dielectric strength of VHB material (a kind of dielectric elastomer) under difference pre-stretch, equal bi-axially or unequal bi-axially. And the strength (maximum voltage can be applied before breakdown) has be greatly improved by these mechanical stretches.
So here comes the question: is the dielectric strength dependent or independent of stretch？
As the 2010 SIMULIA Customer Conference approaches, it reminds me of a thought-provoking presentation given by Dale Berry of SIMULIA at the 2009 SCC in London.
He reminded the audience, of engineers and researchers, that Realistic Simulation is not only good for evaluating mechanical behavior of product performance, but it’s also an indespenible tool for driving innovative research that improves our lives and society.
These notes belong to a course on fracture mechanics
A crack pre-exists in a body. When the body is loaded, the two faces of the crack may simultaneously open and slide relative to each other. The crack is said to be under a mixed-mode condition. When the load reaches a critical level, the crack starts to grow, and usually kinks into a new direction. Subsequently the crack often grows along a curved path.
