A new material formulation to describe nonlinear hyperelastic orthotropic behaviour of composite membranes at finite strains is presented in this article. To provide numerically efficient calculations, a reduced integration scheme avoiding locking and hourglass instabilities is used. Restrictions concerning material parameters are discussed, and material parameters are adapted to experimental data. Numerical calculations are used to demonstrate the potential of the approach to inflated rubber matrix membranes applications.
