Rate Variational Extremum Principles for Finite Elastoplasticity

  • Received Date: 1989-06-20
  • Publish Date: 1990-07-15
  • Dual variational extremum principles for rate problems of classical elastoplasticitv at finite deformation are studied in Updated Lagrangian rate forms.It is proved that the convexity of the variational functionals are closely related to a so-called gap function,which plavs an important role in nonlinear variational problems.
