PBX simulant is known to exhibit highly nonlinear behaviors of deformation such as stress softening-effect. This paper proposes a new pseudo-elastic model for PBX simulant considering stress softening-effect. Simple shear loading and unloading tests at quasi-static states were carried out in order to obtain the mechanical properties of the PBX simulants. and then The Ogden-Roxburgh model is modified to make it consistent with the test result of PBX simulants. Prediction with the new model shows a good correspondence to the experimental data demonstrating that the model properly describes stress softening-effect and the loading-unloading behavior of deformation.
