Transient Analysis of stiffened panel structure by a finite strip-mode superposition method

Abstract

This chapter describes an approach employed for the prediction of linear transient response to dynamic loading of stiffened panels. The method utilizes the semi-analytical finite strip method in conjunction with a modal superposition procedure. Panel properties are developed in the context of first-order shear deformation plate theory, and the ends of panels may be simply supported or clamped. The applied loading, acting normal to the panels, may be of a general nature with respect to both space and time. This approach can be used completely for the analysis of thin or thick composite laminated panels. The chapter also demonstrates the good comparison of the results generated by the developed method and results from the use of other procedures. The prediction of the transient response of stiffened panels to dynamic loading is of considerable interest in various branches of engineering, particularly aerospace and other areas of transportation.
