TY - JOUR AB - A model equation for the prediction of Young's modulus of elasticity of porous materials has been proposed on the basis of an earlier theoretical work on two-phased composite materials. The derivation assumes a definite microstructural spheroidal model and the effective Young's modulus can be given as a function of the volume fraction of closed porosity and the microstructural parameters: shape (axial ratio of the spheroidal pores) and orientation. The theoretical predictions for different pore geometries have been compared with experimental data on porous metals, ceramics and glasses. Good agreement between theory and experiment was found. The microstructural parameters involved in the equation can be obtained from real microstructural data via quantitative microstructural analysis and stereology, no fitting is involved. This fact makes the proposed equation substantial also for practical applications. © 1993, Walter de Gruyter. All rights reserved.
