WebAbaqus is a complex finite element (FE) package widely used in civil engineering practice. The choice of material models for concrete is limited in Abaqus to (i) the smeared cracking model, (ii) the brittle cracking mode and (iii) the damaged plasticity model. The smeared cracking model can handle only monotonic loading that limits the range of ...
