L., Registration Date 12-06-2003 Organization Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine popup.description2 The purpose of work - development experimental - analytical approaches for an estimation of fatigue crack growth in conditions of the mixed mechanisms of fracture. On the basis of the energy approach of fracture the settlement models for definition of the initiation period of fatigue microcrack and its propagation up to macrosizes are constructed. The settlement model for the joint analysis of closing fatigue cracks caused by plasticity and the roughness of their surfaces is developed. The generalized mathematical model for research of fatigue crack growth in elastic - plastic bodies is offered. In frameworks of the probabilistic fracture mechanics the method of an estimation of reliability of welds is developed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
