Hi all
I am modeling a complex muscle with fibre reinforced. The fibre direction is not constant in this muscle. It is changing with the integration point in the model. Is there anyone who got idea on how to simulate the variable fibre directions in Abaqus? Can user subroutine ORIENT do this?
Many thanks,

i have an optimization program for structural problem in Matlab software. i found design variables from Matlab. i want to interface this program in to ansys softare to find optimum stress and strain. how can i interface matlab program in to ansys. if any sample tutorilas please send me.
hi
I constructed a head model, which includes muscle, soft tissue, skin and bone. I wrote user material subroutine (umat) for muscle and soft tissue, seperately. I am going to define the muscle and soft tissues properties by using my umats. However, I dont know how to define two user material subroutines (umat) in one model. The subroutines share the same name: subroutine umat(...). If I assign two umats, ABAQUS will be confused, wont know which subroutine to go. Is there anybody who knows how to sort this out?
Many thanks,
ben
Dear all,
I am improving the cohesive zone model in 2-D proposed by Y.F. Gao to simulate delamination between sub-micron thick films in 3-D. However, I did not find the potential function proposed by Xu and Needleman in 3-D. If you know it please tell me
Here is the potential function proposed by of Xu and Needleman in 2-D (in Y.F Gao’s paper)
The potential function proposed by Xu and Needleman in 3-D ??????
Hi, can somebody give me a hand on where I can get the detailed explanation of VUEL (like UEL in abaqus manul 25.2.19)?
Many thx here.

Surface:
If it's a free surface, the dislocation can penetrate through the surface easily, but, if it's a coating or oxide layer, it will be hard for dislocation to glid out of the surface
Grain boundary:
In discrete dislocation dynamic simulation, some authors take grain boundary as a impenetrable, such as a rigide wall, But in other papers, grain boundary was thought to be a penetrable wall.
So,Is there somthing or simillar property for us to derive.
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.
After some conversation with Roozbeh which are "irritatingly useful" :) I found that this site has done already all the calculations we need http://www.scimagojr.com/ except the list of highlycited papers which remains for me the most interesting aspect and which we seem to need to do manually as we did yesterday with IJSS and JMPS at Most cited papers and H-factor of some mechanics journals -- IJSS
Some results are attached as a big PDF file.
