On a new integration scheme for von-Mises plasticity with linear hardening / F.Auricchio, L.Beirao da Veiga. - In: INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING. - ISSN 0029-5981. - 56:10(2003), pp. 1375-1396.
Abstract:
Limiting the discussion to an associative von-Mises plasticity model with linear kinematic and isotropic hardening, we compare the performance of the classical radial return map algorithm with a new integration scheme based on the computation of an integration factor. The numerical examples clearly show the improved accuracy of the new method.
