Numerical and experimental study of thermomechanical behavior of glassy polymers in the case of large deformations

An experimental research and numerical simulation of thermomechanical behavior of glassy polymers at large deformations are considered. The obtained constitutive equations are linearized for numerical implementation and applied to uniaxial compression case. A series of thermomechanical experiments for lightly-linked epoxy specimens has been conducted. Material constants for constitutive model are obtained. A satisfying accordance of numerical and experimental data is shown.
