Abstract
En 中文
• Revealed influence factors and laws governing fragment velocity distribution. • Three fragment velocity circumferential distribution patterns are clarified. • Design criteria for excellent directional damage efficiency are proposed. • Error of the fragment velocity distribution calculation model is only 6.96%.
