چکیده
|
An efficient technique is proposed for calculation of coupled modes of fluidstructure interaction systems. the algorithm is presented with symmetric matrix operation mentality such that one feels that a symmetric eigenproblem is being solved. furthermore, it is proved that each left eigenvector is related to the corresponding right eigenvector through a simple relation. therefore, subsequent transient analysis can readily be performed. overall, it is felt that the method is very efficient and it is ideal to be employed in general purpose finite element programs for solving abovementioned eigenproblems
