PRoblems of the analysis and generalization data of fatigue tests, new possibility of resource prognosis

摘要

170 years from the moment of the first fatitigue curve construction were the period of accumulation of the data and comprehension of depth of a problem. There has come the period of the analysis and generalization of the experimetnal information, which can be presented conditionally by 5 interconnected sections: a) the equation of fatigue curve; b) scattering; c) similiarity; d) growth of cracks; e) process of accumulation of damage. The prupose of the research is the analysis and generalization of the accumulated information for creation of a unified databank and modern system of the forecast of resource of articles. The basis for decisions acceptance is set of experimental data published in the domestic and foreign literature, and results of 30-years test in NATI of full-scale details of tractors and other mobile machines.
