SOLUTION OF THE CONNECTION PROBLEMS BETWEEN A FINITE HOLED PLATE AND A STIFFENER BY USING THE PARTITIONING CONCEPT OF THE GENERALIZED VARIATIONAL METHOD

In this paper a new finite element method is presented.in which complex functions arechosen to be the finite element model and the partitioning concept of the generalizedvariational method is utilized.The stress concentration factors for a finite holed platewelded by a stiffener are calculated and the analytical solutions in series form are obtained.From some computer trials it is demonstrated that the problem of displacementcompatibility and continuity of tractions between the holed plate and the stiffener issuccessfully analysed by using this method.Since only three elements need to beformulated.relatively less storage is required than the usual finite element methods.Furthermore,the accurary of solutions is improved and the computer time requirements areconsiderably reduced.Numerical results of stress concentration factors and stresses alongthe welded-line which may be referential to engineers are shown in tables.
