✦ Synopsis

Exact integration for the elasto-plastic von Mises Yield Criterion is presented for general stress space. Truncated series solution is obtained under a constant strain rate assumption. On the other hand, a trial and error definite integral solution is obtained under the assumption of constant stress rate. Either could be suitable for the numerical implementation of the model on vector computers and speeding of finite element calculations.

## Abstract In this communication we propose a new exponential‐based integration algorithm for associative von‐Mises plasticity with linear isotropic and kinematic hardening, which follows the ones presented by the authors in previous papers. In the first part of the work we develop a theoretical a
