ABSTRACT
CHAPTER 11
MULTIPLICATIVE DECOMPOSITION
This chapter deals with the formulation of the constitutive theory for large
elastoplastic deformations within the framework of Lee's multiplicative de-
composition of the deformation gradient. Kinematic and kinetic aspects of
the theory are presented, with a particular accent given to the partition of
the rate of deformation tensor into its elastic and plastic parts. The signi-
cance of plastic spin in the phenomenological theory is discussed. Isotropic
and orthotropic materials are considered, and an introductory treatment of
the damage-elastoplasticity is given.
