Fracture locus

Rice and Tracey

AlSi10

The aim of this paper is to calibrate the fracture locus (FL) of an aluminum alloy. The approach used is based on an iterative procedure that involves finite element (FE) simulations and experimental tests. Unidirectional tensile tests on three specimens having different notches were performed to induce different states of stress inside the material. The constitutive law was calibrated using the Voce equation. Experiments were reproduced with FE simulations to extract parameters like equivalent plastic strain at fracture, triaxiality and Lode parameter, successively used for tuning the fracture locus of the considered material.
