EFFECTS OF BOUNDARY CONDITIONS ON FREQUENCIES OF A MULTI-LAYERED CYLINDRICAL SHELL

摘要: Abstract A formulation based on Love's first approximation theory and with beam functions used as axial modal in the Ritz procedure is to study effects of boundary conditions free vibration characteristics for a multi-layered cylindrical shell. Altogether, nine different are considered. Four ends having same end conditions: clamped–clamped, free–free, simply supported–simple supported sliding–sliding. The other five clamped–free, clamped–simply supported, clamped–sliding, free–simply free-sliding. Mode shapes fundamental frequencies also presented. To validate analysis, comparisons frequency parameters those from exact three-dimensional linear elasticity Flugge theory, higher order displacement analysis shear deformation literature made; very good agreement achieved by using present method results available literature.
