Abstract

Free oscillations of an orthotropic conical shell of finite length are considered. This is a problem of the 80s–90s of the last century. Most problems of solid mechanics are described by elliptic equations that have smooth solutions, and, therefore, the development of algorithms that take into account this smoothness is relevant. The paper presents a modern algorithm without saturation and considers specific calculations that show its high efficiency.

正交各向异性锥壳的自由振荡

摘要

考虑了有限长度的正交各向异性锥壳的自由振荡。这是上个世纪80-90年代的问题。固体力学的大多数问题都由具有光滑解的椭圆方程描述，因此，考虑这种光滑度的算法的开发是相关的。本文提出了一种不饱和的现代算法，并考虑了显示其高效性的具体计算。
