Evaluation of elastic and thermoelastic properties of lotus-type porous metals via effective-mean-field theory

The effective-mean-field (EMF) theory, consisting of Mori–Tanaka’s mean-field theory and Bruggeman’s effective medium approximation, was extended in order to calculate the coefficients of thermal expansion (CTE) of composite materials. The effective elastic constants and CTE of lotus-type porous metals, possessing cylindrical pores aligned unidirectionally, were evaluated with the EMF theory.
