拱结构曲杆变形与内力关系的微积分方程推导

Deduction of the Differential and Integral Equations of Deformation and Internal Force of a Curved Bar of an Arch

在分析极坐标下曲杆变形与内力的关系基础上,对直角坐标下平面曲杆内力与变形的微积分关系进行了推导。

Although the relationship between deformation and internal force is studied in some papers, the equation group is unconvenient for programming for its polar coordination form. In this paper, an equation group in Cartesian coordination form,which is convenient for engineering calculation,especially in programming,is dedeucted.
