Abstract

In this study, numerical models based on finite-element method are developed for several applications of fracture mechanics. The use of cracked specimens formed by different material properties has allowed us to analyse the effect of the crack position to the interface and to have a well understanding of mismatch effect for the case of mixed mode of fracture. In other hand, we have noticed that it is very interesting to see the effect of the interface position and loading for the case of symmetrically cracked ring specimen under compression loading.
