Modeling and Characterization of PMMA for High Strain-Rate and Finite Deformations (Postprint)

Abstract

The complex response of glassy polymers to high strain-rate dynamic loading necessitates accurate modeling of these events for comparison with experiments. The strain-rate, temperature and the strain softening behavior are significant and must be considered for large deformations. Several constitutive relationships are discussed in terms of their applicability to modeling PMMA in gap-tests.
