Analysis of Stiffened Plate by Finite Strip Method

유한대판법(有限帶板法)에 의한 보강(補强)된 평판(平板)의 해석(解析)

Various approaches to the analysis of stiffened plating in ship structures have been proposed by a number of researchers. Among them, the finite element method is known to be the most powerful method. However, for many parts of ship's structure having simple geometry and boundary conditions, the F.E.M. is often extravagant and unnecessary. In this paper, the authors have attempted to introduce the finite strip method which was proposed by Y.K. Cheung to avoid the difficulties involved in F.E.M. The results of calculations on the displacements and stresses in various plates with or without stiffeners were satisfactory, which shows the F.S.M. is useful for structural analysis of ship's plating.
