Description
The study aims is to define the strain energy potential for an isotropic hyperplastic material using Mooney-Rivlin method.
The deformation gradient is then passed to UMAT for each prescribed node. The model consist of a rubber strip which act as a housing for metallic chips. The housing is covered by a rubber top which serve as a protective layer for inner material. The rotation and axial force is applied across the two extreme ends and the resulting behaviors is analyzed at the center of the strip. Al linear relationship is observed between a angular/linear deformation and the force applied at the extreme clamps.
