Abstract

A simplified micromechanical model adapted to martensitic transformation is applied to describe transformation induced plasticity (TRIP) in steel. The accommodation of the transformation volume and shape change is performed by plastification considering Hill's anisotropic yield condition. Both a uniaxial and a triaxial loadstress state are investigated. A generalized TRIP-term is developed in the sense of an “extended” Greenwood and Johnson (1965, Proc. R. Soc. London A 283, 430-422) relation.
