Hello Forum Members,
I have a question regarding the implementation of a hyperelastic material model in Abaqus that is active only in the tensile stress direction and not in compression.
For linear elastic materials, Abaqus has a "No Compression" option which ensures that the material definition only applies to tensile loading and not to compression.
My goal is to simulate fibers (as rebar elements) with tensile stiffness only, i.e. no compressive stiffness. Has anyone successfully implemented such a hyperelastic material model, or can provide guidance on how to achieve this in Abaqus?
I appreciate any insight or experience you can share on this topic.
