This paper discusses the principles of a newly developed wave based prediction technique for the steady-state dynamic analysis of thin, flat plates of arbitrary geometry, coupled at an arbitrary angle. This method, based on the indirect Treitz method, expresses the field variables in terms of global wave function expansions. This leads to substantially smaller models compared with the finite element method. The beneficial convergence rate of the wave based method when compared with the finite element method is verified for a validation example. The increasing computational efficiency of this method shifts its practical frequency limitation towards the mid-frequency range.
