摘要:

园柱壳的裂纹问题,特别是在压力容器中,显得非常重要。大量事实说明,压力容器的破坏,主要是裂纹的扩展所导致的。因此,研究这一问题具有十分重要的实际意义,在以往的工作中,大都利用数值法求解园柱壳微分方程。本文是直接用微分方程法求解,其结果与Folias的完全一致。

Abstract: The problem of cracking of cylindrical shells,especially when under inside pressure,appears very important.Many examples shou that it is the crack extension that causes the damage the vessels.Our results completely agree with those that are obtained by Folias with the help of the integral equation
