Advanced analysis of sandwich composite beams: Geometry-driven mechanical and bending performance

Abstract

This study aims to investigate the impact of engineering and mechanical factors on the bending behavior of composite sandwich beams supported by engineering and mechanical factors. Utilizing numerical modeling approaches that were developed with the ABAQUS 2017 software and grounded on basic beam theory, sandwich beams were constructed. The numerical data for the mechanical behaviors were calculated. We studied the bending behavior of two models (I and half-arch) of EN AW-1050A aluminum alloys and resin/glass beams (T300-M800) subjected to an imposed displacement due to bending. We created a reference model based on a simulation of a honeycomb sandwich beam for comparison purposes. The proposed models can be utilized to investigate the flexion of a sandwich beam, supported at one end and exposed to substantial mechanical loads. models, these models possess specific applications in the automotive, civil engineering, and aerospace industries. In terms of energy absorption, the models performed well. In contrast to the other two models, the conventional honeycomb model performed effectively. It displayed a 70% response to pressures, a 58% response to deformation, a 49% superiority to shear stress, and a 46% superiority to displacements.
