摘要：
On specimens of rail steel, experimental research on the propagation features of fatigue cracks of the mixed type is carried out. The direction of the growth of fatigue cracks at three kinds of loading was studied: sign-variable cross shear, and cross and longitudinal shear in the compressing stress field. One general feature of fatigue crack development for all researched specimens is established: the growth of crack direction coincides with a trajectory of the principal stresses, minimal on the module.
