EXPERIMENTAL-MEASUREMENT OF DYNAMIC FAILURE AND FRAGMENTATION PROPERTIES OF METALS

[摘要] An experimental method for determining failure and fragmentation properties of metals in catastrophic breakup events has been pursued in this work. Spherical samples of the test metals were launched at high velocities with a two-stage light-gas gun facility and subjected to controlled impulsive loading by impact on a stationary non-metallic plate. Fragmentation and motion of the debris were diagnosed with multiple flash radiography. Methods for determining critical failure properties and the fragmentation toughness of the test metals were explored.
