The non-axisymmetric confined inflation of an isotropic homogeneous cylindrical membrane is considered in this study. The material is assumed to obey the Mooney-Rivlin constitutive model. The continuum-based formulation is adopted, with the resulting equilibrium partial differential equations, governing the deformation field, solved using a Galerkin based finite element procedure. Upon contact, the inflating material is assumed to stick to the solid boundary. The dependent variables corresponding to nodes which have contacted are then fixed for subsequent deformation. In an attempt to simulate the inflation stage of the blow-moulding process, the method is illustrated through some examples of moulded tapered rectangular bottles with centered and off-centred neck. Examples of initial membranes of uniform and non-uniform thickness distribution are examined. Experiments are carried out in an attempt to validate the theory, in particular, to compare the predicted and measured final thickness distributions of blow-moulded containers.
