An adaptive-scale damage detection strategy based on a wavelet finite element model (WFEM)for thin plate structures is established in this study. Equations of motion and corresponding lifting schemesfor thin plate structures are derived with the tensor products of cubic Hermite multi-wavelets as theelemental interpolation functions. Sub-element damages are localized by using of the change ratio of modalstrain energy. Subsequently, such damages are adaptively quantified by a damage quantification equationdeduced from differential equations of plate structure motion. WFEM scales vary spatially and changedynamically according to actual needs. Numerical examples clearly demonstrate that the proposed strategycan progressively locate and quantify plate damages. The strategy can operate efficiently in terms of thedegrees-of-freedom in WFEM and sensors in the vibration test.
