摘要：

The elastic properties of a FCC hollow sphere metal foam are investigated using FEM. Although its elastic behaviour is well described by a quadratic dependence in density, it cannot be explained by the classical Ashby-Gibson model for cellular solids. A model derived from thin shell elastic properties is proposed. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
