Va. Lubarda et Dj. Benson, On the partitioning of the rate of deformation gradient in phenomenological plasticity, INT J SOL S, 38(38-39), 2001, pp. 6805-6814
The rate of deformation gradient is partitioned additively into its elastic
and plastic parts within the framework of phenomenological plasticity base
d on the multiplicative decomposition of deformation gradient. The correspo
nding partition of the nonsymmetric nominal stress is also given. The resul
ts are compared with the well-known results of partitioning the rates of La
grangian strain and its conjugate symmetric Piola-Kirchhoff stress. Extensi
on to the framework of monocrystalline plasticity is then discussed. (C) 20
