Abstract

A new integration algorithm is described for large strain plastic deformations. The algorithm degenerates to the Euler forward elastoplastic{plastic model for small strain increments and to the rigid{plastic model for large strain increments. The model benets from the advantages of both models: accuracy and fast convergence over a large range of strain increments.
