Numerical evaluation of energy release rate for several crack orientation and position to the bi-material interface plates

Abstract

The finite element method and fracture mechanics concept were used to study the interfacial fracture of bimaterial structure. The effects of mechanical materials properties, position and orientation between crack and the bimaterial interface are developed. The numerical results show that the energy release rate of the interface crack is influenced considerably by these parameters. For the several examples studied, a good agreement is obtained with different authors in term of normalised stress intensity factor and the energy release rate. © Springer Science + Business Media B.V. 2009.
