A shear modified enhanced Gurson constitutive relation and implications for localization

I. A. Khan et al.

Summary: The Gurson model is a widely used phenomenological constitutive relation for ductile failure of structural metals at room temperature, which combines a micro-mechanical basis with computational simplicity. However, it has limited predictive capability for stress states with smaller stress triaxiality. In this study, a shear modified enhanced Gurson constitutive relation is proposed, which maintains the connection with micro-mechanics and improves the predictive capability for a wide range of stress states. The results show good agreement with experimental cell model calculations, and it is found that the critical strain for the onset of localization of deformation is sensitive to the range of void nucleation.

Ductile failure predictions using micromechanically-based computational models

Lars Edvard Blystad Daehli et al.

Summary: Three different micromechanically-based computational models for fracture in porous ductile solids are compared and assessed. The results show that the failure loci strongly depend on the computational model and failure criterion chosen.

A numerical study of a size-dependent finite-element based unit cell with primary and secondary voids

Vetle Espeseth et al.

Summary: This study investigates the effects of dispersoids on the ductile fracture process in aluminium alloys, finding that the size of the dispersoids can impact the growth and coalescence of voids, but not the growth of the primary void.

Ductile fracture of materials with randomly distributed voids

Clement Cadet et al.

Summary: This study provides an extensive analysis of the response of microstructures with random distributions of voids to various loading conditions and characterizes the dispersion of results. It is found that the strain field developing in random microstructures and unit cells feature different dependencies on the Lode parameter, leading to different failure modes and significant dispersion of failure strain.
