Abstract:

Particle reinforced composites are widely used for attaining increased modulus, strength andor 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.
