Identification of Material Parameters for Inelastic Constitutive Models: Stochastic Simulationlastic constitutive models are presented and a principal component analysis is performed to study the correlation structure of the estimated material parameters. The presented simulation method is a suitable tool for various kinds of analysis purposes since the artificial data presents an alternative to a high amount of experimental data.

Some Results Concerning the Mathematical Treatment of Finite Plasticityvolution equation for .. is presented which relates .. to ... The equilibrium equations at frozen plastic flow are now linear elliptic leading to a local existence and uniqueness result without further stability assumptions or other modifications. An extended Korn’s first inequality is used taking the plastic incompatibility of .. into account.

W. F. Bynum,E. J. Browne,Roy Porterom a purely theoretical point of view. The inelastic behaviour is assumed to be governed by evolution equations of the unified type. As the anisotropic formulation considerably complicates the numerical approach, the numerical treatment is developed in full detail. Various numerical examples with applications to shells are presented.
