To the extent of my knowledge I believe that density, elasticity modulus, poisson's ratio, rigidity, bulk modulus are the main factors to build the matrices in ansys. So, where would the software uses yield, tensile, and compressive strength?
Thanks Mr. Omid your answer exactly matched my question
Hi,
Depending on the supported hypotheses in the analysis process required, perfect elastic perfect, elastic perfect plastic, strain hardening.
please see the attached figure
For your case:
Linear Analysis: you do not need yield stress
Plastic Analysis: you need yield stress
But, it depends from the analysis process (Elastic Perfect, Elastic Perfect Plastic, and so on).
I have exported a model with all boundary condition and meshes from ansys workbench to abaqus. the imported model has the same meshes and fixed boundary as in the ansys but the applied force did...
