Jorgen, thanks for your comments. The hydrostatic stress at the failure location is of the same order of magnitude than Von Mises. In its turn Von M...

Jorgen, thanks for your comments. My replies are: 1) Yes, only monotonic loading to failure is of interest. 2) The strain state is far from homogene...

Failure Criteria

Failure Criteria Hi All, we have performed recently a static non linear FE analysis of quite a simple rubber component. Predicted strains are in the...

AnsysUser, feel free to not to quote me on this one but I would have bet that both the linear or the Green strain are used to determine the total mec...

Jorgen, thank you very much for your reply. I performed a search myself, and I have found nothing on triaxial stress fields. Quite a few papers on ...

Jorgen, thanks for your interest. The idea refers to single Kevlar fibers, with the intent of trasferring it later to the composite. We are very li...

Kamini, the neo hookean model is unconditionally stable and should not lead to the same issue. Let us know if you solved your problem. Have a nice...

Foransys, you will find linear viscoelastic models in Ansys named Maxwell and Prony. To my knowledge ( but do not consider it definitive at all) the...

Hi Jorgen, the boundary conditions are given displacements at the inner and outer surface. They then yield exactly the same system for the two cases,...

Jorgen. my question was arguably very badly posed as I of course appreciate your model is a complex viscoelastic one. My question originay ied from a...
