B-splines modeling of free inflation of axisymmetric rubberlike membranes
Résumé
Free inflation of cylindrical rubberlike membranes is examined in this study. The material is assumed to obey the classical Mooney-Rivlin constitutive equation. The membrane profile is interpolated by cubic B-spline functions with natural end boundary conditions. The macro element formulation is detailed. The non-linear system obtained is solved by the Newton-Raphson algorithm associated with an arc-length continuation method. Numerical illustrations are given in order to demonstrate the method efficiency.
