In the present contribution the joint of two orthotropic materials is investigated as the singular stress concentrator and it is modelled as an orthotropic bi-material notch. Such places in constructions are usually responsible for crack initiation and consequently for the final failure of the construction. Within the paper the parametric study of the crack initiation conditions is presented for specific geometry and material combinations and for varying loading conditions. The determination of the crack initiation direction and critical loading conditions is a necessary step in the reliable design of structures with singular stress concentrations.
