INTRODUCTION The number of variables that influence the success of an ACL reconstruction is such that, the use of numerical tools becomes increasingly necessary. In this work, a finite element model is developed to simulate the ACL reconstruction in

We present a simple and robust implementation of the phase field fracture method in Abaqus. Unlike previous works, only a user material (UMAT) subroutine is used. This is achieved by exploiting the analogy between the phase field balance equation and

We present a probabilistic framework for brittle fracture that builds upon Weibull statistics and strain gradient plasticity . The constitutive response is given by the mechanism-based strain gradient plasticity theory, aiming to accurately character

Non-local plasticity effects on notch fracture mechanics

Autor: Emilio Martínez-Pañeda, Susana del Busto, C. Betegón

We investigate the influence of gradient-enhanced dislocation hardening on the mechanics of notch-induced failure. The role of geometrically necessary dislocations (GNDs) in enhancing cracking is assessed by means of a mechanism-based strain gradient
