Elastic and Inelastic Bucking of Cylindrical Plate Structures Using The Finite Strip Method Shahrzad KASAEIAN shahrzad834@yahoo com 5 May 2009 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language persianProf Mojtaba AZHARI mojtaba@cc iut ac ir Abstract This research has been conducted an investigation to the local distortional and lateral buckling of curvedplates based on the classical plate theory Kirchhoff Theory Due to the complexity of the closed form solutions for analyzing buckling of cylindrical plates with differentboundary conditions in this thesis the finite strip method was used as a numerical scheme to solve this problem The assumed curved plate supposed to have simply supported longitudinal edges The plates may besubjected to a combination of longitudinal and circumferential compressions In order to calculate the bucklingmodes and displacements in the plates sinusoidal functions in the longitudinal direction and polynomialfunctions in the circumferential direction have been used The critical stresses and critical moment of curvedplates were obtained by solving an eigenvalue problem In addition to analyze buckling of a flat plate a plate with infinite radius has been assumed and the matricesof stiffness and geometric of the curved plates were modified for flat ones Further investigations have been donein this thesis including study of thickness tapered plates and plates with various curvatures in their cross sectionand also study of plates with various circumferential boundary conditions All these surveys have been conducted in both elastic and inelastic region Analysis of mixed structures consist of either flat and curved plate has been another scope of this research The results of each set of studieshave been elaborated distinctly and the validity of the results has been investigated by comparison with somebench mark problems from literature Key WordsBuckling Curved plate Finite strip Tapered plate Curvature
