Abstract
This is a presentation of a quadrilateral finite element for wrinkled curved elastic membranes. A modified form of the deformation gradient enables us to avoid the spurious compressive stresses generated by a c lassical model. It results in non-linear relations for the eigencompon ents of the Cauchy stress tensor, which are solved by means of a secan t method. The application of the element to sail design is presented i n this paper.
