Investigation of Tensile Behavior of Aluminum foam Used as Sound Insulation

摘要：

　　Aluminum foam with unique reticular structure is used as a sound shield in the railway engineering because of its superior sound absorption.The strength of the aluminum foam plays important role on the life of the shield,so the tensile behavior of the open cell aluminum foam was investigated with the finite element method based on ANSYS software in this paper.The effects of the porosity and the aperture size of the aluminum foam on the tensile behavior are obtained.The results show that the material mechanical properties exhibit a significant decrease as the porosity increases,effects of the aperture size on the mechanical properties of aluminum foam is not obvious.
