Ductile Failure

Abstract

Work under this contract has proceeded in three areas: (i) analyses of ductile fracture processes, with the aim of assessing the capability of analyses carried out within the Gurson constitutive framework for progressively cavitating solids to provide quantitative predictions of ductile fracture; (ii) the development of a finite element methodology for localization and failure analysis in order to carry out fully three dimensional finite element analyses of ductile failure processes and (iii) studies of the effects of fiber volume fraction, geometry and spacing on plastic response and ductile failure in metal matrix composites.
