对能量法及其计算杆系结构位移的探讨
Discussion on the Energy Method and Displacement Calculation of A Bar Structure
摘要
Abstract
The Clapeyron's theorem is proved with the mathematical induction.The Castigliano's theorem can directly be obtained with the Clapeyron's theorem while the strain energy of elastic body is expressed as a general form of the quadratic homogeneous function of load.The displacement calculation of linear elastic bar structure with Castigliano's theorem and the unit load method is the same,but the unit load method based on the principle of virtual work is more universal and more simple,and it's physical meaning is more explicit.关键词
