Abstract : Presented is the foundation of the hybrid stress finite element method for the large deflection analysis of multi-layered aircraft tires. A layer-wise disjoint homogeneous stress field is introduced to facilitate arbitrary stress distribution across the thickness co-ordinate, whose connectivity is established by the interlayer equilibrium conditions. Each layer is an orthotropic ply consisting of textile cords embedded in an elastic rubber matrix. Triangular plate elements are used with five generalized displacements at the nodes. The external loads applied to the tire are inflation, pressure, inertial and nodal contact forces, which are based on the unbounded contact of the shell reference surface with a frictionless rigid and flat plate.
