The study results indicate that there is a soil liner shell outside the mortar liner shell, and the shear strength of the soil liner is obviously higher than the undisturbed soil.

Composite plate and shell with rubber liner can simulate filament wound pressure vessels of the aircraft.

It shows that with the increasing of curvature radius, liner thickness, the length-to-diameter ratio of the charge, and decreasing of shell thickness, the velocity of EFP increase.
