Orthotropic pressure vessels subject to local loads

Differential equations for unsymmetrical loading of simply supported orthot ropic circular cylindrical shell are obtained in terms of displacement comp onents. Then displacement components are expressed in the form of double tr igonometric Fourier series that satisfies the boundary conditions at the en d. Uniformly distributed load on rectangular areas is considered, which is again expressed in terms of double trigonometric Fourier series. Expression s are obtained for displacement components, stress-resultants and stress-co uples. Numerical results are obtained and plotted for a particular case. (C ) 1999 Elsevier Science Ltd.
