Abstract
An approach is proposed for constructing refined generalized models of the durability of composites under extreme conditions based on the modern kinetic theory of strength. Within the framework of variational formulations, effective methods for predicting the defining characteristics (residual life, strength, reliability, durability) of composites under extreme environmental conditions are proposed and developed. Based on conducted research, a method is developed for matching the defining parameters of physical models at the microscopic level with the corresponding defining parameters of mathematical models at the macroscopic level. As a result, we solve the problem of restoring the parameters of physical and chemical processes occurring at the microscopic level and leading to destructive changes in composites and deterioration of their characteristics over time.
