Analysis on strength of the rectangular plate with a hole in case of axial loads

Abstract

The vast majority of aviation structures are areas of stress concentration, it is sufficient to consider riveted or bolted connections. The concentration of stresses mainly found, not only in the area of sharp changes in stiffness, but also in the area of holes. Solving the task of concentration made even more difficult by the complex nature of the loads that come to it. In this article, an inelastic plate with a central half-section under axial loads discussed. This problem was solved for the first time within the framework of the classical theory of elasticity by Kirsch and other version of the solution was proposed by N. Muskhelishvili. The purpose of the article is the software complex MASTRAN and In the MATLAB programming language, we will create an analytical model, the solution of which will approach the analytical solution with high accuracy. As the numerical experiments showed, the calculation scheme modeled in both programs gave us a 1.3% error with respect to the exact solution.
