Implementation of a Modified Unified Viscoplastic Constitutive Model
Original language description
A modified unified viscoplastic constitutive material model is proposed for simulating the temperature and time-dependent cyclic behaviour of the material SiMo 4.06. The constitutive model is based on the non-linear kinematic hardening rule of Chaboche, in which several features are added to incorporate strain rate sensitivity, the strain range dependency of the cyclic hardening, static recovery and mean stress evolution. In addition, continuum damage mechanics is incorporated into the constitutive model. This advanced constitutive model is numerically integrated and implemented into a finite element method analysis as well as into the stand-alone code to simulate the strain-controlled uniaxial low-cycle fatigue tests and the uniaxial creep tests.
