摘要
针对易碎型钨合金具有高的动态压缩强度和低的动态拉伸强度这一特点 ,根据一维应力波理论设计一种测试易碎合金动态拉伸强度的实验方法 .该方法与传统的Hopkinson拉杆试验方法相比 ,克服了螺纹连接和试样截面形状变化带来的误差 ,提高了测试精度 .
A new experimental method was developed to measure the dynamic tensile strength of fragile tungsten alloys. This method is based on the one dimensional stress wave theory and the fact that these alloys possess high dynamic compressive strength and very low dynamic tensile strength. Compared with the traditional SHTB method, the new approach is simple and accurate. It can meet the engineering demands.
