Abstract

There is a need in biomechanics to identify classes of experiments that allow direct determination of constitutive relations while preserving the natural geometry of the tissue. In this paper, we show how specific forms of response functions can be identified for nonlinear hyperelastic membranes by measuring principal stretch ratios, principal curvatures and distending pressures during quasi-static axisymmetric inflation tests. For completeness, we also list all of the equations that are needed to experimentally implement this new constitutive approach.
