Using different types of stress rates in ABAQUS UMAT
Tue, 2015-01-27 03:23 - afallah
Dear friends,
As you maybe know, ABAQUS uses the Jaumann or Green-Naghdi stress rate for large deformation analysis. Recently i found some refrences that show these stress rates leads to major errors for some special cases. Now my question is, how can I change the stress rate used in analysis process using ABAQUS UMAT?
