    boundary conditions effect on material model response

    FEA way, Unfortunately, my problem is not about ill-posed PBC, but rather about it's influence on the material model performance. I don't think that current performance realistic and really want to understand why

    Which output is usually used for stress-strain curvature plot?

    Hello! I suppose, that data in this work could be extracted from Reaction_Force-Displacement in reference point. Then stress is calculated from this reaction force and strain from displacement, that is how it is usually made in ASTM Standards

    Abaqus ductile damage parameters

    Hello! I can suggest you to use the Abaqus Examples-1 problems, 2.1.16 PROGRESSIVE FAILURE ANALYSIS OF THIN-WALL ALUMINUM EXTRUSION UNDER QUASI-STATIC AND DYNAMIC LOADS has several material damage models parameters.

    boundary conditions effect on material model response

    Hello, I'm simulating a Representative Volume Element (RVE) to estimate it's homogenised properties under pure compression in X direction. After some attempts I decided to try just an isotropic material model with one-element simulation, but with the similar boundary conditions, which emulate...
