Application of the Two-Dimensional Hermitian Finite-Difference Method to Linear Shear Deformation Theory of Plates and Arbitrarily Curved ShellsH.Wimmer, Innsbruck, AustriaStarting from the linear, partial differential equations of thin shell theoryincluding the effect of transvere shear deformations a matrix formulationis presented in which all kinematic and dynamic variables appear asdifferential quotients of first order.The transformation of the local field equations into an algebraic form byappropriate two-dimensional finite-difference operators leads to anunsymmetrical banded algebraic equation system from which allvariables requested are directly evaluated.The constitutive equations take into consideration a symmetricallylayered cross section consisting of tangentially isotropic andtransversally orthotropic material. Because of the kinematicassumptions of first approximation shell theory the deformation of thecross section can be seized in an integral sense only.Since the basic equations are formulated in tensor notation with theprocedure presented shells of arbitrary curvature may be analyzed, ofwhich surface is given as an analytic continuosly differentiable function.The algorithm pointed out shows good convergence attributes. Itsefficiency is demonstrated by two examples of which analytical solutionsare known.
