A non-local damage approach compatible with dynamic explicit simulations and parallel computing

• An extended non-local formulation for dynamic explicit simulations. Three dimensional parallel Identification and validation based on simulation-experiment comparisons. Comparison between the implicit gradient micromorphic approaches. In automotive industry, crack prediction is an important step of design: its accuracy crucial to avoid additional development costs delays. However, simulation not always reliable yet which could be explained by use too simple fracture criteria. A possible solution improvement behavior through coupled damage models. Unlike criteria, models consider loss resistance elements behavior, gives a better definition strain localization path. due stress softening, problem becomes ill posed, generating single row elements. The results are then dependent mesh size orientation. To obtain independent results, resort regularization methods, but only few them compatible with simulations, especially ductile failure. This paper proposes extend second approach crash achieved modifying equation ensure robustness implemented enriching under-integrated continuum so as naturally preserve computing ability. comparison simulations experimental obtained specimens machined in dual-phase steel sheet realized validate proposed approach.
