Experimental study on the strain history of critical section during a normal penetration of tungsten alloy shell into a concrete target

Normal penetration of a tungsten alloy shell into a concrete target was performed and the strain history of the critical section of the shell was obtained with the aid of an onboard recording system. Although the tungsten alloy shell undergoes a high stress during penetration, the test results indicate that the shell keeps its integrity. The strain history achieved may provide a basis in shell design and verify theoretical models and numerical simulations of tungsten alloy shell impacting and penetrating normally into concrete targets.
