  • To appraise the technical feasibility of welding thin-walled projectile for penetrating multi-layered reinforced concrete targets, we used the finite element method to simulate the penetration process and designed a set of comparative tests based on the simulation results.The welded thin-walled projectiles were launched from a 100-mm-diameter, smooth-bore powder gun, impacting the multi-layered reinforced concrete targets.A comparative analysis of the structural response characteristics for four projectiles and the damaging effects on the targets were conducted, the optimal techniques and location on the projectile head for the welding were determined, and the joint strength of the projectile tail was measured.These results can serve as reference for the structural design of welded thin-walled projectiles.
