Abstract

For the analysis of prismatic thin-walled structures, whether single or continuous spanned, the finite strip method is one of the most effective methods developed to date. Significant development of the method has been made, in particular, by adopting various analytical functions in the longitudinal direction to suit various support conditions, including the classical beam vibration functions and the spline functions. In contrast to analytically-defined functions, an alternative finite strip method is presented herein by exploring the use of computed beam vibration functions that takes into consideration explicitly the axial-bending coupling effect of unsymmetrical, cross-ply laminates as well as various combinations of boundary and internal support conditions in an easy and unified manner. These functions are computed a priori using conventional finite elements and defined in terms of the usual one-dimensional shape functions. Due to the limited scope of the paper, only one example is given herein to demonstrate the accuracy and effectiveness of the present method for analyzing composite folded plates.
