Abstract:

Since PMMA (polymethyl-methacrylate) is an important material used for the aircraft windshield and canopy, it is necessary to study its mechanical properties. This paper reviews the studies of mechanical properties of PMMA. Constitutive models on viscoelasticity, inelasticity, yield stress and module related to tem-perature are summarized. Recent quasi-static and dynamic experiments are discussed, while several examples in molecular dynamic simulation and finite element analysis are described. The new research directions are commented.
