USE OF THE FINITE ELEMENT METHOD TO DESIGN THE PROPERTIES OF SHAPED JOINTS MADE OF COMPOSITE MATERIALS

摘要

Polskie Zaklady Lotnicze in Mielec within the framework of the BloStEr project implemented in the sectoral program INNOLOT develops technology whose main idea is to be able to connect parts into structures through the use of specially designed shaped joins. The article presents results of numerical analyzes of the selected shape joint made of long fiber composite and verification of analyzes on real object. The second part of the paper presents the results of performed numerical analyzes, which investigated the influence of the change of the layer system on the properties of the joint, in particular the opening force and deformation phenomena of the working elements.
