Vibration and buckling of prismatic plate structures having intermediate supports and step thickness changes

摘要

Description is given of the development and use of a general spline finite strip method for predicting natural fre- quencies and buckling stresses of complex prismatic plate structures. The component plates in general are thin com- posite laminates whose properties are based on t he use of classical plate theory. The assumed strip displacement field allows for the arbitrary location of spline knots in the longitudinal direction and the efficient solution procedure in- corporates multi-level substructuring techniques with the use of superstrips.
