Modelado de los Mecanismos de Propagación de Fisuras en Fundiciones Modulares Austemperizadas Utilizando el Método de los Elementos de Contorno

Abstract

In this work the Dual Boundary Element Method (DBEM) is used to model the micro mechanics of fatigue crack propagation in austempered ductile iron (ADI).
Emphasis is put in devising accurate procedures for the evaluation of the interaction effects between cracks, microcracks and graphite nodules. Obtained results are in agreement with experimental observations. allowing to validate theoretical fracture mechanics models proposed in the literature.
