THE FITTING TECHNIQUE AND RESEARCH OF REGRESSION CURVE BY SHEAR AND TENSILE SYNTHESIS METHOD
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.
