Accuracy of the short fibers reinforced composite material plasticity models

Composite materials reinforced with short high-strength fibers are used in the aerospace industry, due to their high specific stiffness and strength. The anisotropic nonlinear nature of a short fiber reinforced composites requires the usage of anisotropic plasticity model of the material representative volume mechanical characteristics to predict the stress-strain state of the molded products. In this work, was made a comparison of three models...
