The　quantification　of　damage,　in　plates,　pipes　and　such　like　structures,　is　one　of　the　current　research　areas.　In　this　study,　to　estimate　the　notch　size,　shape,　and　orientation　was　carried　out　experimentally　based　on　fundamental　shear　horizontal　mode,　SH0　mode.　Using　least　number　of　transmitters,　the　reconstruction　algorithm　for　the　probabilistic　inspection　of　damage　(RAPID)　has　been　used　to　carry　out　fast　and　efficient　investigation　of　scattered　waves　using　SH0　wave　interaction　with　notch　at　various　incident　angles.　An　approach　of　ultrasonic　guided　waves　and　(RAPID)　algorithm,　using　a　direction-tunable　shear-horizontal　mode　array　magnetostrictive　patch　transducer　(DT-SHMA-MPT),　the　notch　in　a　thin　aluminum　plate　is　experimented.　Firstly,　the　RAPID　algorithm,　based　on　SH0　mode,　is　used　here　to　quantitatively　study　a　notch　in　a　thin　aluminium　plate.　Secondly,　the　imaging　application　using　DT-SHMA-MPT　is　achieved.　Experiments　were　conducted　using　an　array　of　eight　DT-SHMA-MPTs　based　on　a　pitch-catch　mode　to　utilize　the　scattered　waves　at　the　notch.　The　results　obtained　through　experiments　reveal　the　effect　of　directionality　of　the　scattered　waves　and　have　find　out　the　optimal　transducers　configuration.　The　localization,　quantification　and　orientation　at　the　same　time　are　obtained　using　only　two　or　three　transmitters.　To　improve　the　accuracy　of　imaging,　a　threshold　value　was　selected.　The　presented　approach　can　be　used　to　detect,　locate　and　image　the　surface　defects　in　aluminum　plate.　©　The　Authors,　published　by　EDP　Sciences.　This　is　an　open　access　article　distributed　under　the　terms　of　the　Creative　Commons　Attribution　License　4.0　(http://creativecommons.org/licenses/by/4.0/).
