title = "Reduced iterative correction algorithm for coupled vibroacoustic problems",
abstract = "An iterative correction algorithm for coupled vibro-acoustic problems is presented in this paper. FE discretization of the governing equations of the problem results in unsymmetric matrices which require special attention when solved numerically. The main idea underlying the iterative correction algorithm proposed here is to start with the uncoupled system modes computed from symmetric system matrices of the corresponding physics. Using the uncoupled system modes, the algorithm tries to find good approximations of the coupled system eigen-pairs iteratively. The name of the algorithm comes from the fact that the corrections on one physical domain are computed iteratively by considering the effects of the other physical subdomain. In this way, the uncoupled starting modes are corrected to approximate the system response for the coupled problem. At each iteration, once corrections have been computed, the modes and eigenvalues are updated simultaneously through an interaction problem where a symmetrization procedure is used to obtain reduced symmetric matrices.",
