Description	This paper describes a study of the fatigue crack propagation through a material interface of two different elastic materials under assumptions of linear elastic fracture mechanics. Two procedures for estimation of threshold value for further crack propagation from bi-material interface to the second material are suggested. Special attention is devoted to crack perpendicularly oriented to the bi-material interface. The first one is based on modified Sih's strain energy density concept and the second one on the size of area of the plastic zone in front of the crack tip. It is shown that the corresponding fatigue threshold value is strongly influenced by the existence of an interface between two materials. As a numerical example the procedures are in applied on body with protective layer. The calculation of the corresponding threshold values and comparison of both suggested procedures is performed. Both procedures make it possible to decide whether the crack will stop at the interface or will continue g This paper describes a study of the fatigue crack propagation through a material interface of two different elastic materials under assumptions of linear elastic fracture mechanics.
