Effect of particle material on dimensional characters of cratering behaviour in flat target under high speed impact
The article introduces the model of nonlinear compressible plastic medium used to solve the problem of cratering in the flat semi-infinite barrier (target) from AMg-6 alloy under a high-speed impact of a spherical particle of different materials. The authors provide the results of calculations done to measure the depth of the crater in the target material, the pressure and energy on the surface of the crater and in the front of the spherical wave at an impact speed of the particle of 5-8 km / s. Calculated dimensional characters of the craters in the target are compared with the related experimental data.
