Iterative isotropization of the upper and lower bounds for accurate prediction of elastic properties of particulate composites

open access: yesResults in Physics, 2022
The Voigt-Reuss (VR) and the Hashin-Shtrikman (HS) formulas are widely applied to estimate the upper and lower bounds of effective elastic properties of particulate composites, but they are not able to predict the specific values of the properties.
