FIG. 1.

Dependence of the elastic modulus, , on the pore diameter, , for ordered mesoporous silica structures with spherical pores arranged in a simple cubic lattice and density . Results are shown for both tensile and compressive uniaxial straining up to a strain level of 2%.

FIG. 2.

Dependence of the elastic modulus, , on the pore diameter, , for ordered mesoporous silica structures with cylindrical pores arranged in a square lattice and density under (a) uniaxial compressive and (b) uniaxial tensile straining up to a strain level of 2%. In both cases, the calculated modulus as a function of for structures with the same density and spherical pores arranged in a simple cubic lattice is shown for reference. For the structures with cylindrical pore morphology, the insets in (a) and (b) give schematic representations of the loading modes examined.

FIG. 3.

Comparison of the mechanical properties under tension and compression of the mesoporous structures with cylindrical pores arranged in a square lattice for straining in the (a) axial and (b) radial direction based on the results of Fig. 2.
