Modeling of crack behavior in austenitic steel influenced by martensitic phase transformation

Hallberg, Håkan LU and Ristinmaa, Matti LU (2011) In Key Engineering Materials 452-453. p.637-640
Abstract
A thermomechanically coupled constitutive model for finite strain elasto-plasticity is

formulated and numerically implemented. The model gives a physically sound description of an initially austenitic material influenced by martensitic phase transformation. The heat dissipated by plastic slip deformation and by phase transformation is allowed to influence the material behavior and appears as a key influencing factor on the growth of the martensitic phase. The model is calibrated using a common stainless steel as prototype material, allowing numerical simulations of crack propagation to be performed. Alterations of the crack growth behavior are observed as different simulation scenarios are compared.
