在工作中发现不少同志在计算拉伸试验结果时按部就班 ,既比较复杂 ,又容易出错。本文作者通过对计算公式的分析得出了比较简单而又快速的计算方法 ,现介绍如下 :首先 ,假设拉力试棒试验前直径、半径、截面积分别为 do、ro、S0 ,试验后分别为 d1、r1、S1,原始标距长度为 Lo,断裂 During the work, many comrades found that they were complicated and error-prone when calculating tensile test results. The author through the analysis of the formula obtained a relatively simple and rapid calculation method, are introduced as follows: First, the assumption that the tensile test rod diameter, radius, cross-sectional area were do, ro, S0, respectively, after the test were d1, r1, S1, the original gauge length Lo, fracture
