Abstract

The interface in aluminum cenosphere syntactic foam (ACSF) is modeled using FEM to study its deformation behaviour as a function of interface characteristics such as interface stiffness and thickness. The interface is modeled as a thin layer of object. The effective modulus and stress of ACSF examined when it contain 50% cenosphere by volume. In this study, the shell wall thickness of cenosphere is fixed at 1µm. The width of the interface varies from 0.2% to 0.6% of cenosphere volume fraction. The interface strength and modulus varies in the range of 10 to 50% of the matrix alloy. The values of the normalized yield stress and the modulus decrease with increase in the interface width and decrease in the interface strength. The FEM predicted values are also validated with experimental value. The proposed study shows that unit representative shell techniques are reasonably ideal and fast method for predicting compressive deformation behaviour of ACSF.
