Abstract : Presented is the nonlinear finite element analysis of multi-layered aircraft tires. A piecewise parabolic shear stress distribution is introduced to cope with arbitrary stress distribution across the thickness coordinate. Each layer is an orthotropic ply consisting of cords embedded in an elastic rubber matrix. Triangular plate elements are used with five generalized displacements at the nodes. The computer code is written for the CDC-6600 machine under the Scope 3.3 and 3.4.3 operating systems.
