In
flow plasticity theory
the flow plasticity is a
solid mechanics
theory that is used to describe the
plastic
behavior of materials. Shown in the image above is the
plastic deformation
of a
thin metal sheet
. Furthermore, in flow plasticity theories it is assumed that the total
strain
in a body can be decomposed additively (or multiplicatively) into an elastic part and a plastic part. The elastic part of the strain can be computed from a
linear elastic
or
hyperelastic
constitutive model.
