An approach has been proposed for analyzing the causes of failure of parts, which is based on the use of mathematical modeling in calculating mechanical loads and strength parameters by finite-element analysis, followed by an assessment of the durability of the structure using methods of mechanics of damaged media that take into account the accumulation of structural defects in the material of products. The developed approach was used to calculate critical loads that led to the destruction of the crankshaft of a passenger car engine, and to establish the reasons for their appearance, and also allowed to propose technical solutions to eliminate such emergency situations.
