Interfacial Cracks in Dissimilar Orthotropic Materials

EasyChair Preprint 6033

Abstract

The critical state of composite structures features fracture propagation caused by cracks at the interfaces. The conventional assumption based on the fully open-crack model induces to physically unacceptable behavior that oscillatory singularities in stress and displacement fields lead to interpenetration of both faces. These singularities can be neglected by defining the frictionless contact zones of certain length at the tips of interface cracks. Therefore, an analytical treatment based on Ting´s approach is presented for fully open-crack and contact-zone model.

Keyphrases: anisotropic elasticity, dislocations, interfacial cracks, singularities
