An Alternative Mooney-Rivlin Material Model with a Plastic Spin for Finite Strain Plasticity
By: Ladislav Écsi and Roland Jančo
Abstract
Contemporary finite-strain plasticity models that employ the multiplicative decomposition of the deformation gradient exhibit fundamental inconsistencies, as identified in our previous work, likely arising from a misinterpretation of elastoplastic deformation physics. We address these inconsistencies and extend our alternative Mooney–Rivlin model with plastic spin, based on additive strain-rate decomposition, demonstrating its consistency and suitability as a universal finite-strain elastoplastic framework.
