FINITE ELEMENT ANALYSIS OF THREE HOLLOW SANDWICH COMPOSITES ON SIDE COMPRESSIVE PROPERTIES

Abstract

Abstract: On the basis of previous studies, a new structural model was built to study compressive properties of three-dimensional hollow sandwich composites (3D composites) by using the finite element software ANSYS Workbench. The distribution of stress & strain on the fibers, resin and the 3D composites was discussed under compressive loads of 2 mm displacement by using the model. The results show that the maximum value of stress occured between the overlap of piles, where the 3D composites were damaged easily. The minimum value of stress occured on the up and down face-sheet, where the 3D composites were damaged difficultly. The main loads were supported by fibers and the minor loads were supported by resin. The main failure mode of the 3D composites are resin fracture when the 3D composites suffered compressive loads.

Key words: three-dimensional hollow sandwich composites, side compressive properties, finite element software ANSYS, stress, strain, failure mode
