摘要
针对GB/T 228.1-2010给出的3个计算圆管纵向弧形试样横截面积的公式,在计算上且存在着不便或限制的问题,笔者采用数学推导的方法建立了一个统一式,即S0=0.017 44 a(D-a).arcsinb、D-a。应用举例结果表明:采用该公式计算圆管纵向弧形试样的横截面积不仅计算简单,而且结果准确。
To solve the inconvenience or restricted problem of three formulas in GB/T 228. 1- 2010 to calculate cross-section areas of longitudinal arc specimens cutting from the circular tubes, an uniform formula was established by mathematical deducing method, and that is S0=0.017 44a（D-a）·arcsin b/D-a.The application examples results show that using this formula to calculate the cross-section areas of the circular tube longitudinal arc specimens, not only the calculation is simple, but also the result is accuracy.
