| Abstract: | A nonlinear finite element method is used to analyze composite structure consisting of flamentwound solid propellant rocket motor case and revolutionary components in axismmetric large deformationstate. Finite element formulations are given for 8-node isoparametric element and proposal coordinative hyperbolic shell element in aaisymmetric large deformation state. Results of a calculating example are in goodcorrespondance with the theoretical value. |
