✦ Synopsis

A simple microscopic model is proposed to describe the true strain softening and hardening behavior of a polymer glass. Equations of motion for the polymer chain embedded in a polymer matrix have been derived and investigated both analytically and numerically. The model correctly predicts both true strain softening and hardening phenomena. The model also allows a new interpretation of the microscopic origin of true strain softening in a polymer glass.
