For this model, the shear and the bulk moduli
are obtained from the elastic modulus E and the Poisson's ratio v as follows:
Neglecting such details, it is possible to derive  a simple effective medium theory for the porosity dependence of bulk moduli
Unfortunately, we had to use tabulated bulk moduli
in the previous study.
The article presented a new technique to monitor shear and bulk moduli
of rubber for FEA.
Relaxation tests allow the measurement of shear and bulk moduli
at different temperatures, for instance at T = [T.
where [micro] and K are the shear and bulk moduli
for the composite, [phi] is the volume fraction, [less than][epsilon][greater than] is the average shear strain, [less than]e[greater than] is the average dilatational strain, and subscripts m and i refer to the matrix and the inclusion respectively.
As shown for PE, when combined with the concurrent stress variation such data can be used to calculate bulk moduli
using the same formalism as normally applied to elastic solids.
Low strain amplitude single point bulk moduli
were determined using a Mechanical Energy Resolver 1100A.
T] are the complex transverse shear and the plane-strain bulk moduli
