【摘要】 利用一级轻气炮作为加载手段,对AF1410钢的层裂特性进行了研究,获得了AF1410钢的Hugoniot关系、塑性应变率、层裂强度以及层裂片厚度等动态力学参数。对回收的AF1410钢样品进行了断口分析和金相分析,从宏、微观角度分析了AF1410钢在不同应变率下的断裂特性。更多还原

【Abstract】 The spall properties of AF1410 steel are studied with the loading by gas gun.The Hugoniot relationship,plastic strain rate,spall strength,spall thickness and other dynamic parameters are obtained from experimental measurement.By the fracture analysis and metallographic analysis,the spall fracture mechanism at different strain rate is discussed.更多还原
