一、引 言 许多工程构件,如高压气瓶、管道、火炮身管和枪管等,在应力分析时均可作为受内压厚壁圆筒来处理。由于这种力学模型在工程中占据十分重要的地位,因此引起许多力学工作者极大的关注,他们用各种方法做了大量的分析计算工作。但是,已发表的数 I. INTRODUCTION Many engineering components, such as high-pressure gas cylinders, pipes, gun barrel and barrel, can be treated as internal pressure thick-walled cylinders in stress analysis. Because of this mechanical model occupies a very important position in engineering, so many mechanical workers caused great concern, they use a variety of methods to do a lot of analysis and calculation work. However, the published number
