用常微分方程组求解圆孔应力集中问题

SOLUTION OF STRESS CONCENTRATION PROBLEM AT A CIRCLE HOLE BY USING THE CONSTANT COEFFICIENT DIFFENTIAL EQUATIONS

直接利用由应力平衡方程和应力相容方程而得到的常微分方程组 ,求解圆孔应力集中问题。

In this paper,the constant coefficient diffential equations are obtained by directly using the stress equilibrium equations and stress compatibility equations,the stress concentration problem at a circle hole is soved by the diffential equations.Another analytical method is provided for the solution of similar elasticity problems.
