Essay

Means for calculation of critical crack toughness parameter, carrying capacity and fatigue resistance considering the influence of preceding cyclic loading has been suggested. An analytical model for estimation of deflected mode of compressional crooked rod under low-cycle loading has been elaborated. Assessment of effectiveness of calculation of carrying force considering crack toughness criterion of metallic constructions under repeated loading according to the method of mathematical modeling has been represented. An optimal constructive model of structural shapes of the upper chord of crane way girder which excludes appearance of fatigue cracks in the near-joint zone has been elaborated.
