The variational theory of fracture: diffuse cohesive energy and elastic-plastic rupture
Published 2013-04-01“…A first local model is partially successful, but fails to reproduce the strain softening regime. A more robust non-local model, obtained by adding an energy term depending on the deformation gradient, describes many typical features of the inelastic response observed in experiments, including strain localization and necking. …”
