From: On the macroscopic elastic moduli of nanoporous materials with surface tensile and bending rigidity
Equivalent bulk modulus normalized with respect to its classical counterpart (\(\kappa _c\)) as a function of nanovoid radius. Two levels of porosity (\(f=0.1,0.2\)) and two sets of surface bulk and shear moduli are considered: Case 1 (\(\kappa _0=12.932\) nN/nm, \(\mu _0=-0.3755\) nN/nm, \(\eta _0=0\)) and Case 2 (\(\kappa _0=-5.457\) nN/nm, \(\mu _0=-6.2178\) nN/nm, \(\eta _0=0\)).
