  Surface tension at cavity walls can play havoc with the mechanical properties
of perforated soft solids when the cavities are filled with a fluid. This study
is an investigation of the macroscopic elastic properties of elastomers
embedding spherical cavities filled with a pressurized liquid in the presence
of surface tension, starting with the linearization of the fully nonlinear
model and ending with the enhancement properties of the linearized model when
many such liquid filled cavities are present.
