Article Preview

In order to study influence of yield strength of liner on aperture diameter when liner material has high strength, the initial aperture and final aperture diameter were analyzed by considering yield strength of liner material. The relationship of aperture diameter with liner strength changing was obtained. The experiments using Ti alloy liner with different yield strength penetrated into concrete were performed. The results shown that, the average aperture diameter of Ti alloy liner which the yield strength is 785MPa is about 1.16 times bigger than that of copper liner which the yield strength is 870MPa. It has good agreement with theoretic analysis. With liner strength increasing, the aperture diameter decreased, and this increasing is more significant with jet velocity decreasing. With respecting to the high-density copper liner, the influence of yield strength on aperture diameter is more sensitive for low-density Ti alloy liner.
