Purpose. The formation of crack-like defects in rails of railway tracks is a serious problem for engineering practice because of the danger of creating emergency situations. The purpose of this work is to establish theoretically the characteristic an

We develop a basic element of the procedure of construction of the near-threshold part of the diagram of fatigue fracture for metallic materials under the conditions of transverse shear. It is proposed to use a square sample with edge cut and a force

We present a survey of the literature devoted to the models and methods aimed at the evaluation of the contact durability of elements of the tribojoints (in rolling and fretting couples) and analyze the results of investigations in the scientific dir

We study the dependence of the stress intensity factors in a body containing an edge arbitrarily oriented crack on the radius R of rounding of the edges in the base of a rider pressed with unilateral friction to the damaged body near the crack mouth.

We consider the contact problem of the theory of elasticity for a half plane containing an edge oblique crack whose faces are in contact (with friction) under the action of a Hertzian contact load unidirectionally moving along the edge of the half pl

We deduce a singular integral equation of the problem of stress-strain state of a circular disk weakened by a rectilinear nonradial edge crack whose lips are subjected to the action of an arbitrary self-balanced load. For the case of a pressure unifo
