| Abstract Scope |
Plasticity of energetic materials involves various mechanisms, such as shear band formation, void collapse, dislocation movement and these plastic deformations are influenced by microstructure, molecular composition, and the nature of the applied load. Understanding the plasticity and heat conversion under various loading conditions, especially under dynamic loading, is crucial for predicting performance, safety, and reliability. Although numerous studies have been done on this subject, there are still a lot of questions remaining to be answered, especially if the mechanical stimulus is not from a single source. In this presentation, we are going to talk about our recent studies on plasticity deformation of beta-HMX based energetic material under shock loadings. The details of deformation mechanism and heat conversion would be compared for different defect size and different shock loading. Our focus will be on the special of deformation mechanism under multiple shocks and its potential effect on chemical reactions. |
