Abstract

Abstract: A generation program of W-Cu meso-discrete model was developed to investigate the mesoscopic mechanism of tungsten-copper (W-Cu) shaped charge jet formation and the effect of microstructure of W-Cu composites on the jet characteristics. The discrete models of W-Cu liner with different ratios of two phases and various diameters of tungsten particles were successfully established. The multi-scale finite element numerical simulations are carried out on the particle-matrix materials and the referenced equivalent homogeneous material by using AUTODYN-2D Euler solver. The results show that the average velocity of Cu phase is much higher than that of W, leading to a phase segregation and composition gradient in W-Cu jet during its forming process. The content of Cu is higher in the jet tip compared with the liner material while the W particles mainly concentrate in the slug. For the W particles with same size, the relative change amount of W content in the jet increases with the decrease in W content in the original materials. For the same component content, the W content in jet decreases with the growth in the diameters of tungsten particles. The composition gradient is more sensitive to the size of W particle in jet with higher W content. Key
