    Harijono Djojodihardjo1, Irtan Safari2

    CMES-Computer Modeling in Engineering & Sciences, Vol.91, No.3, pp. 205-234, 2013, DOI:10.3970/cmes.2013.091.205

    Abstract A series of work has been carried out to develop the foundation for the computational scheme for the calculation of the influence of the acoustic disturbance to the aeroelastic stability of the structure. The generic approach consists of three parts. The first is the formulation of the acoustic wave propagation governed by the Helmholtz equation by using boundary element approach, which then allows the calculation of the acoustic pressure on the acoustic-structure boundaries. The structural dynamic problem is formulated using finite element approach. The third part involves the calculation of the unsteady aerodynamics loading on the structure using generic unsteady… More >
