Problem of contact data in ABAQUS 6.8 version

Submitted by jin haeng Lee on

Hi.

I have an issue related to recent change in ABAQUS new version.

 I've recently found a problem related to cotact data in ABAQUS new version, 6.8. I use fil files, but I've heard from a Simulia engineer that data file also has the same problem (I have not checked it out yet.)

Johnson-Cook Material Model, Abaqus Explicit

Submitted by D. Barrett Hardin on

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

Submitted by sudheesh on

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.
