查询词典 shear steel

The results show that dynamical ductil-ity dominated final velocity of fragments. During tube expansion, the shear fracture appears preferentially a-long the adiabatic shear bands under positive stress, so the adiabatic shear band determines the size and shapeof fragments. Though the fragmentation behaviour of medium carbon Si - Mn bainific steel is close to that ofsteel 50SiMnVB, medium carbon Si - Mn bainitic steel is an ideal candidate material for the tubular bombs be-cause it is better in dynamical ductility, which can enable the tubes to gain high speeds before fragmentation.

结果表明：材料动态塑性是决定破片最终速度的主要因素；圆管膨胀时外表面形成以剪切为主的裂纹，并向内扩展，接近内表面的绝热剪切带伴随着圆管的膨胀而扩展，并未出现失稳现象，但在正应力的作用下成为优先的断裂通道、决定破片的尺寸和形态；中碳Si-Mn贝氏体钢与50SiMnVB钢的破碎性能相近，但贝氏体钢动态塑性很更好，破碎前的膨胀量较大、更有利于提高破片初速，是弹箭比较理想的候选材料。
