EXPERIMENTAL STUDY ON FLEXURAL BEHAVIOR OFSANDWICH BEAMS WITH TRANSVERSE RIBS

Abstract

Abstract: This paper explores the flexural performance of sandwich beams with transverse ribs in four point bending tests. The effects of the thickness and space of the ribs on the failure modes, stiffness, ultimate bending strength and ductility properties of the sandwich beams were obtained. Test results indicates that the transverse ribs can change the failure mode of the sandwich beams. The beam without transverse ribs failed in core shear failure, while beams with transverse ribs failed in a more ductility failure mode. The transverse ribs can significantly increase the ductility properties of the sandwich beam with a maximum of 229%. The smaller the rib space, the better ductility performance.

Key words: composite material, sandwich beam, transverse ribs, bending performance, ductility
