    Transient dynamic analysis of dam-reservior interaction by coupling DRBEM and FEM
    Küçükarslan, S; Coskun, SB
    In this paper, time domain dynamic analysis of dam-reservoir interaction is presented by coupling the dual reciprocity boundary element method in the infinite fluid domain and the finite element method in the solid domain. An efficient coupling procedure is formulated by using sub-structuring method. Sommerfeld's boundary condition for far end of the infinite domain is implemented. To verify the proposed scheme, numerical examples are carried out to compare with the available exact solutions and results of the finite-finite element coupling.

    Transient analysis of dam-reservoir interaction including the reservoir bottom effects
    Küçükarslan, S; Coskun, SB; Taskin, B
    In this paper, time-domain transient analysis of elastic dam-reservoir interaction including the reservoir bottom effects is presented by coupling the finite element method in the infinite fluid domain and in the solid domain. An efficient coupling procedure is formulated by a substructuring method. Sommerfeld's boundary condition for the far end of the infinite domain is implemented. To verify the proposed scheme, numerical examples are given to compare with available exact solutions for rigid and elastic dam cases. Finally, a numerical example is studied to evaluate the effects of the reservoir bottom. (c) 2005 Elsevier Ltd. All rights reserved.
