Abstract

This article proposes a new type of aluminum-wood composite beam that reduces material weight and enhances lightweight construction. The beam is reinforced by composite material plates, providing additional rigidity. The beam has three cross-sections: I-shape, U-shape, and rectangular tube, with adhesive connection for both interfaces. The interfacial stresses in aluminum-wood composite beams reinforced by composite laminates are analyzed using nonlinear elastic theory and strain compatibility approach. The model considers shear deformations of the interface and is intended to be applied to all types of bonded materials. Theoretical predictions are compared with existing solutions, contributing to understanding the mechanical behavior of the interface and designing aluminumwood structures reinforced by composite materials.
