A Model for Plastic-Hydrolytic Damage Bioresorbable Polymer Composites
Abstract: This paper explains and assesses a recently developed constitutive model for elastic-damage that may sustain plastic-hydrolytic damage. When a metallic material is subjected to plastic strain, voids and microcracks in the metal matrix start to form, develop, and merge. This is what causes ductilitydegradation in metals. Only a few of the many models that have been presented to depict ductile failure have done a thorough analysis of the entire damage …
