The focus of this Minisymposium is on recent advances in the ductile fracture of materials, with an emphasis on failure under non-proportional loading, complex matrix behaviors and complex void morphologies. Both experimental and modeling contributions are welcome. Particularly welcome are contributions that combine experiment and modeling. Experimental contributions of particular interest concern the physical mechanisms of ductile fracture under non-proportional loading paths at various strain rates and their interaction with localized plastic flow. Qualitative as well as quantitative studies of such phenomena using modern experimental facilities are especially welcome. Ductile fracture modeling issues of particular interest are: the competition between ductile damage accumulation and localization phenomena to understand and model shear failure; the role of material anisotropy; the role of material heterogeneities; and identification procedures for ductile fracture model parameters. Numerical aspects are also of interest, including algorithmic issues and practical numerical implementations of constitutive formulations aimed at providing objective predictions of ductile failure.
