Resolución de Problemas de Mecánica de la Fractura Aplicando el Método de los Elementos de Contorno Dual

Gemma Rodríguez, Bernardi Sensale, Ignacio Iturrióz


The present work is concerned with the application of the Dual Boundary Element Method for linear elastic crack problems under mixed-mode conditions.
The stress intensity factors evaluation is carried out by the Crack Opening Displacement at collocation points extremely close to the crack tip or by the Jintegral decomposition method wich is applied on a citcular path, defined around
each crack tip.
Finally several examples are analysed and the computed results are in excellent agreemet with values from the literature.
