Elastic properties of mullite and mullite-containing ceramics - Part 1: Theoretical aspects and review of monocrystal data

Original language description

In this first part of a two-paper set on the elastic properties of mullite and mullite ceramics the current literature is reviewed and, based on the available monocrystal data, a mutually consistent average set of elastic constants for polycrystalline mullite materials at room temperature is calculated and optimized via minimization of the total average relative root mean square (RMS) deviation. Based on the results of this paper, the recommended values of adiabatic elastic constants are 224.9 GPa for the Young modulus, 87.8 GPa for the shear modulus, 170.9 GPa for the bulk modulus and 0.281 for the Poisson ratio. The RMS deviation of this set is lower than for any other set and thus these values exhibit a high degree of mutual consistency with respectto the elasticity standard relations. Micromechanical upper bounds and model relations are summarized for describing the porosity dependence of elastic moduli, and a simple relation is used to estimate the difference between adiabatic an
