Crack Resistance of a Shaft in Flexure with Rotation

  • D. S. Dobrovol’skiiEmail author


For more reliable prediction of the life of structural elements, an energy criterion of crack resistance corresponding to nonlinear failure mechanics is proposed: the critical effective shape energy. On the basis of fatigue tests of 15 model shaft elements in flexure with rotation, the crack resistance of the shaft is assessed as a function of the depth of the annular cracks.
