Determination of the Characteristics of Cyclic Crack Resistance of Steels Under Transverse Shear (A Survey)

摘要

We present a survey of works devoted to the investigation of the fatigue fracture of steels under the conditions of transverse shear. Numerous methods aimed at the determination of the characteristics of cyclic crack resistance of structural steels of different strength classes are analyzed. The analysis of the results of investigations enables us to make a conclusion about the necessity of improvement of the available methods and development of new methods for the construction of the kinetic diagrams of fatigue fracture with regard for the influence of friction of the lips of fatigue cracks on the stress intensity factor K (II) and the elimination of stresses in the vicinity of the crack tip.
