Abstract
Novel numerical analysis aspects involved in the algorithmic treatment of a recently proposed formulation of thermoplasticity at finite strains are discussed. Two key aspects in these new developments are: i. The formulation of a new class of return mapping algorithms for multiplicative decomposition which inherit without modification all the features of the standard algorithms restricted to the infinitesimal theory; ii. The development of a new class of staggered coupled algorithms for coupled problems which retain the key property of unconditional stability. The work reported on herein summarizes some of the recent developments at Stanford in the area of inelastic coupled thermomechanical problems at finite strains.
