It is difficult to extract the result I need from .fil file, because it is a complex file to read/rearrange . So I decided to use the .res file. This file is a binary format. I really appreciat your idea about how to read this file.

Thank you so much.

problem using crystal plasticity model in Abaqus via UMAT

Crystal plasticity

I am trying to model polycrystal behaviour using Abaqus Umat via crytalplasticity . My Umat results for single crystal & about 5 grain, are reasonable, but when, I try to use more than 5 grain in each integration point (polycrystal model) abaqus aborted with following message after about 15 increment:

Abaqus Error: The executable C:\SIMULIA\Abaqus\6.10-1\exec\standard.exe aborted with system error code 693...

I will be happy if someone guide me about this problem.

Help needed on VUINTER to define molecular interaction between two surfaces

Submitted by pphl on Wed, 04/27/2011 - 11:32

Hi,

Does anyone have any idea on using VUINTER to define adhesive contact between a hard body and a soft body (the potential between the two surfaces is molecular like van der waals or lennard-jones potential).

Kinetic Monte Carlo

I wnat simulat rollong process. Mteral deformation is simulated by FEM and i want simujlate microstructure evolution by KMC method. Do any one have experience in this field (coupling FEM and KMC) ?

Monte carlo

I want simulat micro strucure evolution in metal fromind, e.g. rolling. To capture grain growth or refinement, i use MC method and rolling process simulate by FEM method (ABAQUS). Do any one have experience in this field?

An interesting arXiv paper: "Precession optomechanics"

Submitted by Ajit R. Jadhav on Wed, 04/27/2011 - 07:26

Mechanics of Photonic Devices

Hi all,

Just thought that the following paper archived at the arXiv yesterday could be of general interest to any mechanician:

Xingyu Zhang, Matthew Tomes, Tal Carmon (2011) "Precession optomechanics," arXiv:1104.4839 [^]

The fig. 1 in it makes the matter conceptually so simple that the paper can be recommended to any mechanician for his general reading, and not only to a specialist in the field.

Regarding JLTYP in DLOAD in Abaqus

Submitted by pphl on Wed, 04/27/2011 - 06:57

Hi,

Reference need for VUINTER, VDLOAD in ABAQUS

Submitted by pphl on Wed, 04/27/2011 - 05:12

Can someone please post some material/good links to get better understandng of using these subroutines (other than ABAQUS documentation itself).

Thanks in Advance.
