Strength Analysis of Layered Sandwich Beam

Abstract

Sandwich beams are composite systems that have properties such as high rigidity, high strength and low weight. The sandwich system include glass fiber reinforced polymer (GFRP) skins and phenolic cores, and several layers of sandwich panels are bonded with an epoxy polymer matrix to manufacture the packages. In sandwich beam (LSB) layers, four horizontally oriented layers and the other four vertically oriented layers were tested. To understand the basic behavior of a multilayer sandwich beam, a 3D finite element model was developed using ANSYS. To explore the suitability of this new concept for structural applications, the flexural behavior of the layered sandwich beam is validated using data available in the literature, and the numerical model can be improved by incorporating shear and fatigue behavior which increases confidence in using this novel concept of beam in the civil construction sector.
