    Development of a new curved beam element with shear effect (1996)

    Notes: Two-noded curved beam elements, CMLC and IMLC, are developed on the basis of Timoshenko's beam theory and curvilinear co-ordinates. These elements are developed by the separation of the radial displacement into the bending and the shear deflection and the projection of the shear deflection into bending deflection. In the CMLC element, field-consistent membrane strain interpolation is adapted for removing the membrane locking. The CMLC element shows the rapid and stable convergence on the wide range of radius, thickness and length of the curved beam. The field-consistent membrane strain and the separation of radial displacement produce the most efficient linear element possible.

    Notes: In this study, advanced computational analysis system for nonlinear static aeroelasticproblems has been successfully developed by the composite structure (FEM)-fluid (CFD) combinedmethod with internal iteration steps. Major focus of the present study is to investigate the staticaeroelastic characteristics of laminated composite wings including the strong normal shock waves inthe transonic and low-supersonic flow regions. The results importantly indicate that the effect ofairfoil camber on the load distribution of laminated composite wing models can be nonlinear due tothe variation of ply orientations

    Analysis of crack closure problem using the dual boundary element method (1996)
    Springer
    International journal of fracture 77 (1996), S. 323-336

    Notes: Abstract A numerical procedure of the crack closure problem solved by the dual boundary element method is developed in this paper. The dual boundary element method is used to allow for the solution to a general mixed-mode crack problem with a single regional formulation. The frictional contact problem on the crack surface is formulated with the complementary problem adapting the Coulomb's friction law. Several examples are shown to demonstrate the validity of the present procedure.

    Variational formulation for Timoshenko beam element by separation of deformation mode (1994)
    Chichester : Wiley-Blackwell
    Communications in Numerical Methods in Engineering 10 (1994), S. 599-610

    Notes: A variational formulation for a Timoshenko beam element is derived by the separation of the deformation mode into the bending deflection and shear deflection. Shear deflection is projected into bending deflection and the projection matrix is constructed by using the equilibrium equation and the relation of force and displacement. The exact stiffness matrix of the Timoshenko beam element can be obtained by the present method. Examples are solved in order to show the effectiveness of the beam element in comparison with other elements.

    A computational method for frictional contact problem using finite element method (1994)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: Using the finite element method a numerical procedure is developed for the solution of the two-dimensional frictional contact problems with Coulomb's law of friction. The formulation for this procedure is reduced to a complementarity problem. The contact region is separated into stick and slip regions and the contact stress can be solved systematically by applying the solution technique of the complementarity problem. Several examples are given to demonstrate the validity of the present formulation.
