The structural acoustic properties of stiffened shells [PDF]
The Journal of the Acoustical Society of America, 2008 Plates stiffened with ribs can be modeled as homogeneous isotropic or orthotropic plates, and modeling such an equivalent plate numerically with, say, the finite element method is, of course, far more economical in terms of computer resources than modelling the complete, stiffened plate.
