The Analyses about Axisymmetric Deformation of a thin pressure vessel by orthotropic composites

Orthotropic 복합재료로 만든 두께가 얇은 압력용기의 변형에 관한 연구

The analytic solution of displacements of thin cylindrical pressure vessel made by carbon fiber T700/Epoxy was obtained using equilibrium equations of orthogonal curvilinear coordinate system. Equilibrium equations with the assumed displacement field were derived from a reasonable description of the behavior of thin elastic shells using principle of virtual work. Some analyses of the theoretical solution are presented and compared with the results of hydraulic tests of the pressure vessel.
