摘要
Using the LS-DYNA dynamics simulation software and tracer testing technology, the formation process of jet formed by hemispherical shaped charge liner and the pressure of micro-elements changing with time were simulated. With research of the parameters of the axial stress's second peak value and duration of micro-elements on the top of liner, equivalent stress of micro-elements on the border of jet and slug and stress difference of micro-elements inside and outside of axis, the relationships between the stress distribution and rod-like jet formation of micro-elements were obtained. The results show that when the cone angle is in the range of 100 to 110 degrees and the wall thickness is 0.07d, the better rod-like jet can be obtained.
