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

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.
