其他摘要：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.
