用莫尔-库仑准则描述了大块非晶合金剪切断裂对垂直于剪切面的应力的依赖性。然而，缺乏对其适用性的系统验证。我们使用一种独特的测试夹具，能够控制（i）剪切断裂的位置和（ii）断裂平面上的法向应力与剪切应力的比值，对大块金属玻璃进行测试，以检查Mohr-Coulomb准则的适用性。(C)2008 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
The Mohr-Coulomb criterion has been invoked to characterize the dependence of shear fracture of bulk metallic glasses on the stress normal to the shear plane. However, systematic verification of its applicability is lacking. We use a unique test fixture that is capable of controlling (i) the location of shear fracture and (ii) the ratio of the normal to shear stress on the fracture plane to perform tests on bulk metallic glasses to examine the applicability of the Mohr-Coulomb criterion.
