FTMP-based Description of Substructural Instability-induced Ductile Fracture

Abstract

FTMP-based realizations of ductile fracture modes in single crystal and polycrystals models are presented. The fracture modes in the current context stem from destabilized dislocation substructure spontaneously evolved in the deformationinduced manner, strongly depending on the crystallographic orientations and their combination. Duality diagram representations enable us not only to visualize the associated energy flow but also how the excessively-stored strain energy are redistributed into incompatibility-related underlying degrees of freedom.
