Metallogenic geological characteristics of Longgang polymetallic belt in central Yunnan;

Based on MOCL algorithm, jet formation by wide angle shaped charge and penetration into multi layer targets are numerically simulated with a two dimensional multi material Eulerian code.

In order to obtain the multilayer metal plates with stable property after welding,the spaces between two metal plates are regulated,an impact plate is added,and the explosive welding experiment on the seven-layer and eleven-layer aluminum plates are done.
