Application of the efficient wave based prediction technique for the steady-state dynamic analysis of flat plates

The use of the new wave based (WB) method, instead of the finite element (FE) method, for the steady-state dynamic response analysis of flat plates is considered. The mathematical background of the WB method is discussed in detail, where much attention is paid to the least-squares formulation. The comparison of both prediction techniques applied to an uncoupled plate problem illustrates the better convergence properties of the WB method with comparable computational costs. The introduction of a performance improvement further increases the computational efficiency of the WB method.
