Modeling the Change in Shape of Low-Cycle Inclined Semi-Elliptical Cracks
Modeling of the spatial low-cycle crack kinetics for refined service life and survivability of elements of aviation, rocket and space, nuclear, and other critical equipment is studied. The results of experimental studies and numerical calculations of the parameters of shape change are presented, taking into account the characteristics of the microrelief and the complex surface of low-cycle fracture of inclined surface semi-elliptical cracks. A functional relationship is shown between the mesostructural characteristics of low-cycle fragmentation of the surface of the cracks under study with parameters of nonlinear fracture mechanics such as the strain intensity coefficient and the specific elastoplastic work of fracture at a certain point of the defect contour.
