FINITE ELEMENT ANALYSIS ON ANISOTROPY OF 3D COMPOSITE UNIT-CELL MODEL

Abstract

Abstract: 3D composite unit-cell model was created by PRO/E 5.0 mapping software. Compressive property of unit-cell model under multipronged compressive loading were simulated with the help of the finite element software ANSYS. The stress distribution of the unit-cell model was investigated and analyzed. Meanwhile, taking the unit-cell model subjected to compressive loading in X direction for example, the stress distribution of fibers and resin matrix was analyzed. The results showed that 3D composite was obviously anisotropic under compressive loading,manifesting as the best compressive property in X direction and the worst compressive property in Z direction. Fibers made the major contribution to subject the compressive loading, while the resin matrix made the minor contribution to subject the compressive loading.

Key words: finite element, 3D woven composite, unit-cell model, compressive property, anisotropy
