A non-linearly elastic, finite deformation analysis applicable to the static mechanics of excised lungs.
Continuum mechanical analyses of lung behavior require a constitutive relationship for the parenchyma. For a homogeneous, isotropic, elastic material this relationship is dependent upon the strain invariants. Furthermore, the sparse data available indicate that the relationship should be exponential in form. A suitable equation has previously appeared in the literature. In this paper it is developed for application to whole lung experiments.
