Development of Explosion Model of Energetic Materials Considering Shock to Detonation Transition and Damage by External Impact

외부 충격에 의한 손상을 고려한 화약과 추진제의 폭발모델 개발

A pressure-based BOIK model considering Shock to Detonation Transition(SDT) and damage due to external fragment or bullet stimuli impact on energetic materials and analytical approach for determination of free parameters are proposed. The rate of product mass fraction(${\lambda}$) consists of ignition term that represents the initiation due to shock compression and growth term that describes propagation of detonation wave and strain term representing the morphological deformation induced by external impact.
