Исследование напряженного состояния в упругой пластинке из композиционных материалов с бесконечным рядом одинаковых круговых отверстий

Abstract

The present article is based on the theory of anisotropic linear elasticity using the complex variable. A analytical method for solving macroscopic stress concentration in orthotropic plates with holes is presented. In this work, stress functions satisfying the boundary condition for the anisotropic plate with holes. In this study, a plate under uniaxial tension is considered and the border holes are free from any pressure. The article contains the most important results of research on the concentration of stresses of around holes. In this article the stress near a circular hole was calculated by orthotropic fibre-reinforced plates for four different composite materials. The analysis of the concentration in composite plate is, however, considered as a homogeneous orthotropic material. The results of research dependent upon the distances between the centers of the holes. Also this problem is analysed with the finite element method by package ANSYS. In addition, the results of the analytical method with numerical method are compared.
