摘要： A test fixture for simultaneously testing two material test samples is provided. The fixture provides substantially equal shear and tensile stresses in each test specimens. By gradually applying a load force to the fixture only one of the two specimens fractures. Upon fracture of the one specimen, the fixture and the load train lose contact and the second specimen is preserved in a state of upset just prior to fracture. Particular advantages of the fixture are (1) to control the tensile to shear load on the specimen for understanding the effect of these stresses on the deformation behavior of advanced materials, (2) to control the location of fracture for accessing localized material properties including the variation of the mechanical properties and residual stresses across the thickness of advanced materials, (3) to yield a fractured specimen for strength measurement and an unfractured specimen for examining the microstructure just prior to fracture.
摘要翻译：提供同时测试两个材料测试样品的测试夹具。夹具在每个试样中提供基本相等的剪切和拉伸应力。通过逐渐对夹具施加载荷力，两个试样中只有一个断裂。在一个样品断裂时，固定装置和载重工作台失去接触，第二个试样在破裂之前保持镦锻状态。夹具的特殊优点是（1）控制试样上的拉伸剪切载荷，以了解这些应力对先进材料的变形行为的影响，（2）控制断裂位置以获取局部材料性质，包括在先进材料的厚度上的机械性能和残余应力的变化，（3）产生用于强度测量的断裂试样和用于在断裂之前检查微结构的未断裂试样。
