Dear All,
Could you suggest any literature or online step by step tutorial on how to create your own subroutines in ABAQUS like umeshmotion or umat. Any relevant information would be much appreciated. I am looking for information that are not covered in the ABAQUS manual.
Thanks very much in advace,
Nicholas

Held at TU Dresden, Germany, September 7-10, 2009.
Dear all,
I am looking into coupling the molecular dynamics code LAMMPS with ABAQUS FEA package. Do you have any information about this? Maybe a research group that is currenlty working on this or any relevant publications?
Thanks in advance,
Nicholas
Consider attached file.It lists the details of the Timoshinko method for geometric non linear analysis.
Can anyone tell me how is it diiferent from incremental analysis conceptually?
Is it used commercially?Which method is more sophisticated-Timoshinko,incremental or Newton Raphson?
Please help
I am trying to use finite element modeling of indentation experiments
to extract hyperelastic material parameters. I am having a dilemma,
when the tissue has residual strain, the model couldn't achieve the
high nonlinear relationship between displacement vs reaction force as
measured in the experiments.
I have tried several strain energy potentials,
1) W=A/B*{exp[B(I1-3)]-1}
2) W=C10(I1-3)+C01(I2-3)
3) W=C10(I1-3)+C20(I1-3)^2+C30(I1-3)^3
4) Arruda-Boyce type model
I am currently running a Quasi-Static compression simulation in Abaqus Explicit using the Johnson-Cook Plasticity option. As the strain gets beyond the elastic range, the stress-strain response begins to oscillate +- 5 MPa around the expected curve. Does anyone know why this is happening and/or how to repair the problem?
Thanks,

Inorder to find out the residual stresses and distortions in butt weld due to thermal loads in steel plates, i have used
shell57 for thermal and shell43 for structural.The material properties used are temperature dependent.
I carried this out in two steps.
The thermal analysis is carried out first.
A moving heat source is used to generate the temperature distribution on the plate.
HELP WANTED
I am looking for a graduate student or a Postdoc who is interested to work on a research project in modeling and simulation of self-healing surfaces and related topics.
The candidate is expected to major in Mechanical Engineering or Materials Science (background in surface mechanics / physics / tribology is preferred), to be comfortable with computational software (MATLAB, Ansys or similar), and to be enthusiastic about producing modeling/computational results and preparing publications.
