Structural Response of Sandwich Beams with Different Facing Materials Subjected to Bending

Article Preview

Abstract:

Sandwich elements with structural functions are widely used in engineering applications, offering outstanding advantages, such as high strength and stiffness compared to its low specific weight. The sandwich elements consist in two stiff and thin faces, separated by a thick and lightweight core. A numerical analysis is performed in this paper, in order to evaluate the flexural structural response of sandwich beams with foam core and various facing materials. It has been noticed that the deflections decrease when the stiffness of the facings increase. The results are represented in terms of maximum deflections and direct stress distributions.
