Abstract

Thin-walled toroidal shells are widely used in the construction and facilities of present-day design. During operation, various defects arise on the surface of the shells, in particular local dependings. The article describes a model of a fragment of the toroidal shell with a local deepening based on three-dimensional finite elements with cubic approximation of the original variables. The influence of the defect depth on the stress distribution is investigated.

局部缺陷的环形壳的仿真

摘要

薄壁环形壳体广泛用于当今设计的结构和设施中。在运行期间，在壳体的表面上会出现各种缺陷，特别是局部缺陷。本文介绍了一个环形壳的局部局部加深模型，该模型基于三维有限元，原始变量的立方近似值。研究了缺陷深度对应力分布的影响。
