Calculation and Experimental Analysis of the Stress-Strain State for Inclined Semielliptical Surface Cracks

Resumo

Numerical calculation data on the characteristics of linear and nonlinear fracture mechanics are presented. These characteristics help to predict the surface development of studied cracks before their initiation on the surface of a product. In addition, they provide the specified durability and strength evaluation of important elements of equipment with consideration of the kinetics of the local fracture processes along the contours of differently oriented semielliptical surface cracks with consideration of the local dimension of the stress state and their relative depth.
