Gurson’s Model: ALE Formulation and Strain Localization.

This paper presents a brief review of Gurson’s damage model, employed to describes the strength degradation in ductile metals submitted to large plastic deformations. The damage model is applied using finite elements and an Arbitrary Lagrangian-Eulerian formulation (ALE), to ensure a better quality to the finite elements mesh. The study of the combined application of ALE and Gurson approach to damage modeling and strain localization is the object of this paper. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
