Modeling of Crack Resistance of Structural Elements at Complex Nominal Stress State
The method for modeling the crack resistance of structural elements with a complex nominal stress state according to the characteristics of crack resistance of models under uniaxial nominal loading was proposed on basis of the developed criterion of destruction and the formulated concept of the equivalence of mechanical states. Application of the method is shown by examples of modeling the fracture toughness of shafts with different variants of combinations for bending with rotation and for torsion according to the experimental characteristics of the crack resistance of models under conditions of bending with rotation.
