Macroscopic Finite Element Simulation of Brittle - to - Ductile Failure of SENB Specimen

Abstract

The aim of this paper is to present macroscopic finite element simulations of brittle - to - ductile failure of single edge notch bend (SENB) specimen. The primary brittle - to - ductile transition presents brittle fracture and propagation of central crack, which may be stopped by a ductile inclusion. The secondary propagation of cracking after passing the ductile inclusion is beyond the scope of our paper. An adaptive FE mesh fixed along the crack path is proposed. [...].
