摘要
通过与其他诸如单向拉伸、压缩试验的比较,描述了剪切试验识别材料流动曲线的优点;阐述了金属材料剪切试验的研究现状,按照试验过程中试件变形区的应力状态,将剪切试验分为简单应力状态下的剪切试验和与其他加载方式结合的复杂应力状态下的剪切试验;介绍了各种剪切试验方法的试验装置和典型试件形状,概述了各类剪切试验的实现方式,并根据各种剪切试验方法的优缺点,概括了各个剪切试验的应用现状。
The advantages of shear tests for identification of the flow curve of metallic material were described by comparing the other test methods, for example, uniaxial tension/compression test. The research on metallic material shear tests was reviewed in this paper, in which the tests were divided into two kinds of shear tests according to the stress state of deformation zone during testing, i.e. shear test under simple stress state and shear test under complex stress state result from other loading methods. All kinds of devices and typical geometries of specimens were introduced and the loading methods of shear tests were described in this paper. The applications of all kinds of shear test were summarized according to the advantages and disadvantages of shear test method.
