Influence de la forme du pliage sur la résistance des tôles

Abstract

This research focuses on the impact of bend geometry on the mechanical properties of sheet metal used in industrial structures. The study compares three main configurations: plain sheet metal, U-bent sheet metal, and V-bent sheet metal. Through numerical simulations performed using Abaqus and by imposing realistic boundary conditions, the results show that bent shapes significantly improve stiffness and reduce deformation compared to flat sheets. This study highlights that optimizing the bend shape is an effective solution for strengthening sheet metal, improving its stability, and meeting the industry's increasing demands for reliability and performance.
