General spline finite strip analysis for buckling and vibration of prismatic composite laminated plate and shell structures

A general spline finite strip capability is presented for predicting the buckling stresses and natural frequencies of prismatic plate and shell structures which are composed of composite laminated plate and/or shell panels that may have arbitrary lay-ups. The prismatic structures may have general cross-sections and boundary conditions. This method is developed in the context of first-order shear deformation plate and shell theory as well as the classical plate and shell theory and a massive substructuring technique is incorporated into the solution procedure. A considerable range of types of application is described and a particularly interesting one shows that the general spline finite strip capability has great flexibility in matching the boundary conditions specified on the entire structures.
