In the present contribution the joint is modeled as a bi-material wedge. The singular character of the stress field near the wedge tip is investigated. Depending on the geometry of the wedge and the selection of the materials, the stress field can have two singularities. Correspondingly the singular stress field is expressed as a sum of two singular terms with different stress singularity exponents. It is shown that to study the problem of a crack onset at the wedge, both two terms have to be taken into account. First, the angle of the direction of potential crack initiation is determined. Then a criterion for crack nucleation and propagation in the selected direction is formulated Pracoviště Ústav fyziky materiálu Kontakt Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Rok sběru 2006
