The strength enhancement of open -cell aluminum foam with hollow struts has been studied through finite element method using three dimensional, periodic unit cells models for solid and hollow struts of open-cell aluminum foam under compressive uniform load. The stress behavior and deformation of these models has been analyzed at constant relative density. The results show that open-cell foam with hollow struts has better strength than the solid strut model. The simulated results are compared with other analytical published data and it shows good agreement.
