Johnson-Cook Material Model, Abaqus Explicit

ABAQUS

Johnson Cook Plasticity 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,

Weld analysis using ansys

weld and plasticity

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.

Batch mode simulation error Advise me

software

Hi,

I am running ANSYS on batch mode to simulate a composite lamina (one

layer) with some pattern is cut through, like 4 circular holes.

I would like to do this analysis for different angle of fibers, so I

used SHELL 99 and applied *DO and *ENDDO. But after reading the output

with Matlab I perceive some errors occur in not the first iteration

but all the single ones after the first.

The thing I have done was reading the displacement of each node around
