Численный метод решения задачи Сен-Венана о кручении стержня двусвязного сечения методом конформного отображения

Abstract

A numerical method for solving the Saint-Venant problem about torsion of a shaft with an arbitrary two-connected section domain was developed. This method is based on preliminary building of a conformal mapping of this domain onto a circle ring followed by the solution of the reduced boundary Dirichlet problem. The testing of this method with employment of computer programs demonstrates its sufficiently high efficiency and precision.

Разработан численный метод решения задачи Сен-Венана о кручении стержня с произвольной двусвязной областью сечения. Метод основан на предварительном конформном отображении данной области на круговое кольцо и последующем решении редуцированной краевой задачи Дирихле. Опробование метода с использованием компьютерных программ показало достаточно высокую его эффективность и точность.
