Dynamic failure of ductile materials

Résumé

The failure of ductile materials subject to high loading rates is notably affected by material inertia. We analyze how strain localization and fracture are influenced by inertia through selected topics comprising dynamic necking, fragmentation, adiabatic shear banding and dynamic damage by micro-voiding. A multiscale modeling of the behavior of voided visco-plastic materials is proposed that extends classical models by including microscale inertia. Applications to spalling and dynamic fracture reveal that microscale inertia has first order effects on results.
