Instrumentation and procedures for estimating the constitutive parameters of inhomogeneous elastic membranes.
Biomech Model Mechanobiol. 2002 Dec; 1(3):211-8.BM

Abstract

This study presents a method for estimating the spatial variations in material properties of elastic membranes, such as biological tissue, which contain both inhomogeneous strain fields and inhomogeneous material properties. In order to validate the method, an inhomogeneous, isotropic rubber membrane was biaxially loaded to obtain a set of states. A neo-Hookean finite element model, together with the measured strains, was used to estimate the material parameters by minimizing the residuals between the measured and modelled residual on surface tractions.
