    Generalized stress intensity factors Hk (GSIFs) are the necessary parameters
    to describe stress state near bi-material junction tip by means of asymptotic
    series. GSIFs can be determined as a least square method solution of overdetermined
    system of linear equations. The equations consist of analytical eigenfunctions,
    which are determined as a solution of eigenvalue problem and results
    of finite elements analysis (FEA), in form of displacement or stress components.
    The study presents the application of the overdeterministic method on bi-material
    junction problem. The effect of number of input values from FEA and the radius
    of their extraction on resulting Hk is studied. The study also shows how number
    of calculated singular and non-singular terms affects values of individual factors.
    The results are compared with results of the Psi-integral method. Once the GSIFs
    are determined, stress solution on particular diameter by asymptotic series is
    compared with pure FEA results.
