Abstract
The OASIS computer code presented herein is in essence a nonconventional finite-element code, which incorporates the closed-form asymptotic solutions derived by Fettahlioglu and Steele, (1974), Fettahlioglu and Wang (1977) for orthotropic layered shells of revolution subjected to axisymmetrical temperature and surface load distributions. OASIS also encompasses the stability analysis of orthotropic nonhomogeneous shells of revolution. Additionally, it is capable of performing analyses of the following special topics of complex nature:a)Interlaminar-shearing stresses in orthotropic layered shells of revolution (Fettahlioglu, 1986)b)Shallow spherical and paraboloidal shells subjected to axisymmetrically distributed loads (Fettahlioglu, 1969)c)Shallow spherical and paraboloidal shells subjected to anti-symmetrically distributed loads (Fettahlioglu, 1969)d)Exact solutions for the natural frequencies, phase and group velocities of elastic traveling waves in orthotropic layered cylindrical shells (Fettahlioglu, 1984)e)Analysis of the junction of an arbitrary number of shells of revolution with an elastic ring (Steele, 1966)
