Analysis of fatigue and durability of thin-walled Structures using the ANSYS software package

Abstract

It is widely known that solving the issues of durability of aircraft structures is one of the most difficult issues, despite the fact that a number of scientific articles or monographs are devoted to the study of this issue, an ideal method still does not exist. As a result, it is very difficult to accurately determine the number of flights or the calendar period on an airplane. That is why they resort to conducting physical experiments on aircraft under multiple static loads, which is very significant in financial and time terms. This article not only presents general issues of fatigue and durability, but also reports on the durability of a specific structure as a numerical experiment, evaluating all the parameters that determine its performance over a certain period of time under cyclic loads. A specific example shows the service life, damage and safety factor of the bracket.
