Elastic constants of MgB2 from acoustic measurements using sintered porous samples are much different from the values by ab initio calculations. This paper considers the discrepancy in terms of the pore shape with micromechanics modeling. The model calculations showed that ab initio calculations are consistent with the values corrected for the oblate ellipsoidal pores from the measured elastic constants, and the extremely small values can be measured with sintered samples.
