    Abstract
  • This paper describes the measurements of the punching shear fracture strength of LY-12 aluminum alloy from room temperature to 400 ℃, and the static shear strength in the same temperature range. The ratio of the dynamic punching shear to the static is about 1.3∶1 at room temperature to 4∶1 at 400 ℃. It shows that the high temperature dynamic strength is considerably higher than that of static.
