【摘要】 分离式Hopkinson压杆是对准脆性材料实施高速加载的理想工具,利用该装置可以对准脆性材料实施各种加载方式,测定材料的动力特性参数。对分离式Hopkinson压杆装置的测试原理做了扼要说明,简单介绍了目前用于准脆性材料的测试方法(压缩实验方法和拉伸实验方法),并结合目前的测试技术,对准脆性材料的实验方法提出了一些新的设想。更多还原

【Abstract】 The Split Hopkinson Pressure Bar(SHPB) is an ideal tool in carrying out high-speedloading to quasi-brittle materials, it can afford many loading means loading means to mensurate materials properties under dynamic loading. This paper compendiously explains the testing principle of SHPB, and introduce the testing means for quasi-brittle at (compress experiment and tensile experiment), references currently testing technique, advances some new advices.更多还原
