Abstract
The key features of the regulatory requirements for the fatigue life valuation of composite laminates were presented. With allowance for those requirements and through the use of the well-known patterns of residual strength degradation and stiffness degradation of layered composite materials over the course of fatigue cumulation, the fundamental principles of the methodology of substantive fatigue life valuation were created. They, in particular, can be used for the lower and upper wing paneling of the transport category of aircraft. It was indicated that it’s worth making the substantive valuation at the project definition stage of an aircraft, when the key par...
