Wave-based prediction analysis for dynamic-response problem in non-convex domain

Wave-based method (WBM), which is derived from indirect Trefftz method, is a new novel deterministic prediction technique for analyzing structural dynamic-response problems in the mid-frequency range. WBM has geometrical limitations, which can be overcome through complement-graph conception by introducing the multi-level modeling theory. To illustrate the feasibility and efficiency of WBM, the dynamic-response process is implemented using a thin-plate structure as a numerical example. The numerical result extends the ability of WBM to deal with the dynamic problem in concave domain.
