Calibration of a Distornional Hardening Model of Plasticity
Original language description
Directional distortion hardening is manifested by the distortion of the shape of the yield surface such that a region of high curvature develops roughly in the direction of loading while a region of lower curvature develops in the opposite direction. Recently, several models were proposed. The simplest one studied, makes use of the Armstrong- Frederick rule, having five independent parameters. The analytical solution for uniaxial cyclic test is derived together with that for the stabilized cyclic response. The evolving shapes of the yield surfaces and their sensitivity to inputs parameters are analysed. An algorithm for material constants fitting is proposed.
