摘　　要：阐述了板料剪切试验的研究现状,按照板料夹持方式将其分为螺栓多点夹持、夹头集中夹持和板面压紧夹持;介绍了各夹持方式的典型装置和试样,根据夹持力的施加方式分析了受力状态,按照与纯剪受力状态的近似程度进行评定,得出了3种方式的优劣评价.Domestic and international research on sheet metal shear tests was reviewed in this paper, in which the tests were divided into three types, that is, multipoint bolt clamping, linear concentrated clam- ping, and surface uniform clamping, in accordance with the sheet clamping method. The typical devices and samples of each clamping method were introduced. According to the way of clamping force applied, the stress states were analyzed. Based on the approximation to the simple shear stress state, judgments from different characteristics of the three methods were acquired.
