PBX is known to exhibit highly nonlinear behaviors of deformation such as the Mullins
effect of stress softening, hysteresis, residual strain, and frequency dependant responses. This paper
proposes a phenomenological energy-based model for PBX considering the Mullins effect for
isotropic, incompressible, hyperelastic, particle-filled materials. Uniaxial compressive loading and
unloading tests at quasi-static states were undertaken in order to obtain the mechanical properties of
the PBX simulants. The phenomenological energy-based model by Ogden-Roxburgh is, then,
modified to make it consistent with the test result of PBX simulants in the case that the Mullins
effect is dominant. Prediction with the new model shows a good correspondence to the
experimental data demonstrating that the model properly describes the Mullins effect and the
loading-unloading behavior of deformation.
