摘要
研究介绍了一种通过单一方法的数据,利用其幂函数和线性方程,以解方程的数学方法直接求得二元幂函数曲线,为使方程更加简单,将单剪强度与拉脱强度相乘并开方后得到几何平均强度,将二元函数转换为一元函数,形成复合变量,新的拟合曲线物理意义明确,简单直观,自变量无需对号入座,曲线使用方便,精度与二元函数基本相同.
Abstract
Study introduces a single method of data,using its power function and linear equation,and directly obtaining a binary power function curve by mathematical method of solving equations.In order to make the equation simple,multiply the single shear strength with the pull-out strength and take the square solution to obtain the geometric average strength,and convert the binary function into a single function to form a compound variable.The new fitting curve has clear physical meaning,is simple and intuitive.Independent variables do not need to be matched,the curve is easy to use,and the accuracy is basically the same as that of binary functions.
