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 clamping, 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.
