Measurement of Shear Performance of Q345+304 Composite Sheet
摘 要
研究了总厚度≤10 mm的Q345低合金钢+304不锈钢复合薄板抗剪性能的压剪测试方法,并将其与传统拉剪测试方法进行了对比,同时分析了搭接长度对抗剪性能测试结果的影响。结果表明:压剪测试方法可以用于复合薄板抗剪强度的测试,试验结果重复性偏差≤10 MPa,无横向剥离力的存在,避免了拉剪方式的弊端,测试结果能更真实地反映Q345+304复合薄板的抗剪性能;压剪试样界面搭接长度增加,测得的抗剪强度降低,因此在满足标准要求的前提下,尽量使用搭接长度较小的试样进行压剪测试。
Abstract
The compression-shear test method to measure the shear performance of Q345 low alloy steel + 304 stainless steel composite sheet with total thickness less than or equal to 10 mm was studied and compared with the conventional tensile-shear test method. The effect of overlap length on the test results of shear strength was also analyzed. The results show that the shear strength of the composite sheet could be measured by the compression-shear test method, and the repeatability deviation was less than or equal to 10 MPa. During compression-shear test which could avoid the shortcomings of the tensile-shear test method, there was no lateral peel force, so the test results could truly reflect the shear performance of Q345+304 composite sheet. With the increase of interface overlap length of compression-shear specimens, the measured shear strength decreased. Therefore, under the premise of meeting the standard requirements, specimens with small overlap length were preferred to carry out the compression-shear test.
