Young's modulus of porous brittle solids
Kalyan Kumar Phani,S K Niyogi +1 more
TL;DR: In this article, the porosity dependence of Young's modulus of brittle solids has been described semi-empirically, and a new equationE =E0 (1 −aP)n whereE andE0 are the Young's Moduli at porosity,P, and zero, respectively, a andn are material constants, has been derived semi-EMpirically.

The Elastic Constants of a Solid containing Spherical Holes
TL;DR: In this article, a self-consistent method for the estimation of the shear modulus and the bulk modulus is proposed, where each hole is surrounded by a spherical shell of real material, and the reaction of the rest of the material is estimated by replacing it by equivalent homogeneous material.
