ABAQUS/Explicit

Submitted by alex_612 on

Hi,

Does anyone know how to convert the result of Abaqus/Explicit from .sel file to .fil.

I run a analysis and generate the .sel file. Then, I use commond:

abaqus job=[file name] convert=all

The convert process is completed but i cannot file any .fil file. Does anyone know the reason?

Thank youv very much

Extended Chaboche viscoplastic model for cyclic loading

These days I've been applying oneself to implement the Chaboche viscoplastic model in ABAQUS user-subroutine for simulating the cyclic loading in single crystals.

The procedure can easily get out. I'm not sure about the problem, the deduction of Jacobian, the convergence? 

Btw, I know there is free subroutine for crystal plasticity by Huang YG. I wonder if the UMAT routine for chaboche model is available, then I can generalize it to fit for my case.

How to model a viscoelastic material on ANSYS?

I am a mechanical engineer in Turkey in senior year. As a graduation project I have to model soft tissue cutting operation by using ANSYS. The main aim in the project is;

1.Choosing
the correct material properties (SOLID,SHELL etc.) and correct
method( Prony Series or Generalized Maxwell for
viscoelastic)

2.Creating a cylindirical model as an example
and than creating the orginial model as a representation of the soft
tissue(in this case the tissue must be some living organ ex:liver )

3.By
using the contact modeling (I learned that it requires to have some
detailed experience in writing subroutine) dividing the material into
