Abstract

THIS PAPER PRESENTS AN APPROACH TO PREDICT DUCTILE FRACTURE OF REAL-LIFE STRUCTURES. IT RELIES ON ROUSSELIER'S CONSTITUTIVE MODEL TO DESCRIBE PLASTIC VOID GROWTH, A SPECI¯C FINITE STRAIN FORMULATION THAT PRESERVES ENERGETIC PROPERTIES AND A NONLOCAL THEORY TO DEAL WITH STRAIN LOCALISATION. IT IS APPLIED TO COMPUTE THE FRACTURE OF A NOTCHED SPECIMEN.
