Investigating the Strain Rate Effects on Cumulative Damage in a Highly Filled Polymeric Material

Abstract

Particle reinforced composites are widely used for attaining increased modulus, strength and/or toughness depending on the application. Such composites exhibit nonlinear constitutive response due to various factors such as damage (debonding, cavity or vacuole formation, cracking), hysteresis during loading-unloading (Mullins effect), and viscoelasticity. Such nonlinear behavior is observed extensively in filled polymer or rubber products such as toughened plastics, tires, and solid propellants. A number of studies have been performed to address one or more of the issues contributing to the non-linear behavior of these composites (1-4).
