一、前言近年来从理论上描述材料在冲击载荷作用下产生高速变形的力学性质,已有很大的进展。另一方面,由于测试技术的进步,在实验研究中测得了定量描述这些力学性质的数据,从而解决了比以前更加复杂的工程问题。实验研究的基本途径是测量应力波的传播及其材料或结构的响应。测量应力波的方法很多,其中锰铜压阻应力计就是应用较多的一种。我国在锰铜压阻应力计的研制和应用方面取得了一定
I. INTRODUCTION In recent years, great progress has been made in theoretically describing the mechanical properties of materials that produce high-speed deformation under impact load. On the other hand, due to the advancement of testing techniques, the data quantitatively describing these mechanical properties were measured in experimental studies, thus solving more complicated engineering problems than before. The basic approach to experimental research is to measure the propagation of stress waves and their material or structure response. There are many ways to measure stress wave, among them, the manganese-copper piezoresistive stress meter is one of more applications. China in the development and application of manganese copper piezoresistive stress gauge made some progress
