Numerical study of the impact of constitutive modelling on the evolution of necking in the case of a tensile test on C68 grade steel.

Résumé

This article deals with numerical simulation of necking. It draws the attention onto the importance of the description of strain hardening and the effects on the evolution of necking. In order to compare necking evolution in relation with different plasticity models, a tracking procedure which consists in determining the evolution over time of discharged elements of the sample is adopted. Models that take into account physical phenomena at the microscopic level and especially the heterogeneities of materials from a mechanical point of view seem well suited to fit experimental evidence connected to necking.
