The　paper　presented　damage　localization　of　plate-like　structures　using　stationary　wavelet　transform　(SWT)　of　displacement　mode　shapes.　SWT　is　a　redundant　transform　which　doubles　the　number　of　input　samples　at　each　iteration.　It　provides　a　more　accurate　estimation　of　the　variances　and　facilitates　the　identification　of　salient　features　in　a　signal,　especially　for　recognizing　noise　or　signal　rupture.　The　displacement　mode　shapes　of　a　cracked　plate　that　contains　a　crack　of　small　depth　are　essentially　smooth　surfaces.　In　reality,　the　mode　shapes　contain　very　small　local　peaks　or　discontinuities　in　the　region　of　damage.　However,　it　is　difficult　to　identify　and　locate　a　crack　directly　from　the　graphical　plot　of　the　displacement　mode　shapes.　Using　SWT,　mode　shape　curves　can　be　decomposed　into　smooth,　low　order　curves,　called　approximation　coefficients,　and　wavy,　high　order　curves　called　the　detail　coefficients,　which　include　defect　information　that　is　useful　for　damage　localization.　The　modal　responses　of　the　damaged　fixed　plates　with　a　small　crack　ratio　of　5%　were　computed　using　the　finite　element　method　(FEM).　The　results　show　that　the　SWT-based　method　has　great　potential　in　damage　localization　of　plate-like　structures　as　it　does　not　require　the　modal　parameter　of　an　intact　plate　as　a　baseline　for　damage　localization.　Therefore,　it　can　be　recommended　for　real　applications.　Copyright　©　2012　by　ASME.
