Effect of effective shearing area on result of direct shear tests;
有效剪切面积对直剪试验结果的影响分析
The influence of stress state and shearing area on the shearing strength is studied.
剪切面积和应力状态的变化对剪切强度有着重要的影响,分析了剪切面积和剪切位移在剪切过程中的变化,剪切面积对剪切强度的影响随着剪切位移量的增大而呈现非线性增大的趋势。
The results indicated that impact absorbed energy of heat-affected zone in welded joint of X70 pipeline steel were proportional with shearing area on the whole.
结果表明:X70管线钢焊接接头热影响区冲击试样的冲击功与断口剪切面积基本成线性比例关系,冲击功越高,剪切面积越大。
