Derivation of nonlinear shell models combining shear and flexure: application to biological membranes

Olivier Pantz and Karim Trabelsi

Vol. 3 (2015), No. 2, 101–138
Abstract

Biological membranes are often idealized as incompressible elastic surfaces whose strain energy only depends on their mean curvature and possibly on their shear. We show that this type of model can be derived using a formal asymptotic method by considering biological membranes to be thin, strongly anisotropic, elastic, locally homogeneous bodies.
