固体推进剂动态力学行为研究进展
Research progress in dynamic mechanical behavior of solid propellants
摘要
Abstract
The current situation about dynamic mechanical behavior of solid propellants was summarized from the aspect of dynamic mechanical characterization,damage mechanism,dynamic fracture and dynamic constitutive models.Analysis results show that dynamic mechanical experiments focused on the parameters such as initial elastic modulus,yield stress and strength;the filler particles fracture was the main form of dynamic damage;the dynamic fracture mainly concentrated in the field of crack initiation,and three types of dynamic constitute models were reviewed.On this basis,the future key research directions were also briefly presented,considering that deepening experiment research,mechanical numerical simulation research and the exploitation of thermo-visco-hyperealstic dynamic constitutive model incorporating damage will be the focus of future research.关键词
