Abstract

A system of recurrent constitutive relations is written for the brittle fracture probability at micro-, meso-, and macroscale levels, and fatigue curves on defect levels are plotted at the one frequency symmetric loading, consisting of a finite number of blocks with different amplitudes and number of cycles. The results of calculations at different regimes of two block loading for 0.25% carbon steel are in satisfactory agreement with the known experimental data.
