Abstract
The work is devoted to the study of damage accumulation processes in solving problems on the fracture of bodies with crack-like defects. Scientific publications in the field of studying the influence of various parameters on the results of numerical simulation are considered. The boundary-value problem of the deformation and fracture process is determined, the degradation algorithm is written taking into account the staging and the dispersion of the strength properties of finite elements over the three-parameter Weibull distribution. The results of numerical simulation are presented in the form of a calculated diagram of deformation in the axes “force - displacement” and patterns of the fracture area, patterns of development of defects. The influence of the stochastic nature of the strength properties of the material on the fracture process is shown.
