Buckling and vibration analysis of composite plate and shell structures using the PASSAS software package

摘要

A description is given of the PASSAS finite strip software package for predicting the buckling stresses and natural frequencies of composite laminated prismatic plate and shell structures of complicated cross-section and general lamination. The basic equations underpinning the development of the properties of a transversely curved finite strip are presented in the context of first-order shear-deformation shell theory and, by reduction, in the context of thin shell theory. The B-spline finite strip method is used and this enables the specification of a wide range of end conditions.
