摘要:
线性装药聚能药柱起爆后能产生高速射流，为了研究线性装药聚能药柱的爆轰和射流的形成过程，该文应用无网格MPM法进行三维数值模拟，采用显式算法对爆轰产物和射流的速度、密度以及压力分布进行了数值计算。无网格MPM法与有限元和其他无网格法相比，能获得比较好的模拟结果，而且在数值计算效率方面具有优势。
Abstract:
Linear shape charge may produce high speed jet once high explosive is detonated. To study the detonation process of the high explosive and jet formation of the linear shape charge, a threedimensional numerical simulation program is developed by using the material point method (MPM). Velocity, density, pressure distribution of the jet and the detonation products are computed and studied based on explicit algorithm. In comparison with FEM and other meshless methods, MPM has the advantages of a robust result and a higher computational efficiency.
