The methodology for development a nonlinear defining relation for a unidirectional carbon fiber reinforced plastic (CFRP) was proposed. The methodology is based on the analysis of stress-strain curves at different strain rates and loadings at different angles to the reinforcement direction. The study is based on the relations of the hereditary theory of elasticity and the anisotropic theory of elasticity using the Volterra principle and the properties of resolvent operators. Physical nonlinearity was taken into account by applying the Rabotnov curve of nonlinear deformation using piecewise linear approximation.
