摘要: 本文在椭圆坐标系下,借助于贝塞尔函数乘积形式的马丢函数,并依据Neober的简化原理[1],利用微分方程法直接求解薄壳微分方程,得到了带环向钝裂纹受拉圆柱壳(见图A)裂顶附近的带有p钝修正项的弹性应力场方程。

Abstract: In an elliptical coordinate system,we directly solved the cylindrical shell differential equations and obtained the equation for the elastic stress fields with σBlunt additional term around the tip of circumferential blunt crack in the cylindrical shell subjected to tension by using Mathieu function of the multiplied kind of Bessel function,following Neuber's reduction principle and utilizing the differential equation method.
