Integration method for constitutive equation of von Mises elastoplasticity with linear hardening
This paper presents a summary of the new semi-analytical integration method presented in [10] for von Mises elastoplasticity model with combined linear isotropic-kinematic hardening within a small deformation range. Solutions for the case of constant strain rate and constant stress rate assumptions are also presented. Furthemore, it is shown how the general solution reduces to the particular ca...
متن کاملA TFETI Domain Decompositon Solver for Von Mises Elastoplasticity Model with Combination of Linear Isotropic-Kinematic Hardening
In this paper we present the efficient parallel implementation of elastoplastic problems based on the TFETI (Total Finite Element Tearing and Interconnecting) domain decomposition method. This approach allow us to use parallel solution and compute this nonlinear problem on the supercomputers and decrease the solution time and compute problems with millions of DOFs. In our approach we consider a...
متن کاملImplementation of a Generalized Midpoint Algorithm for Integration of Elastoplastic Constitutive Relations for Von Mises’ Hardening Material
This paper presents a detailed description of the computer implementation of a generalized midpoint algorithm for integration of constitutive relations for von Mises’ hardening material. A nonlinear scalar equation for determination of the plastic multiplier is derived. The solution of this equation for a hardening material, by the Newton-Raphson method, usually converges in threefour iteration...
متن کاملA Variational Principle for Hardening Elastoplasticity
We present a variational principle governing the quasistatic evolution of a linearized elastoplastic material. In case of linear hardening, the novel characterization allows to recover and partly extend some known results and proves itself to be especially well-suited for discussing general approximation and convergence issues. In particular, the variational principle is exploited in order to p...
متن کاملApproximations for Von Mises
We prove Edgeworth expansions for degenerate von Mises statistics like the Beran, Watson, and Cram er-von Mises goodness-of-t statistics. Furthermore, we show that the bootstrap approximation works up to an error of order O(N ?1=2) and that Bootstrap based conndence regions attain a prescribed conndence level up to the order O(n ?1).
