16MnR/0Cr18Ni9Ti复合钢板损伤与断裂过程的声发射特性试验

Experiment on Feature of Acoustic Emission for 16MnR/0Cr18Ni9Ti Composite Armor Plate in the Damage and Fracture

摘要: 研究了16MnR/0Cr18Ni9复合钢板在承受拉伸载荷时的损伤与断裂行为。给出了损伤类型、阶段和恒载等关键声发射特性, 发现了不同损伤类型表现出不同的声发射特性。损伤与断裂的不同阶段, 可用声发射信号的几种关联图进行区分。

Abstract: The damage and fracture of composite armor plate of 16MnR/0Cr18Ni9Ti in the state of trending were researched. It was discovered that different damages showed different acoustic emission feature, and different stages of damage in composite armor plate could be differentiated by some relational graphs of acoustic emission signal.
