In　recent　investigations,　the　application　of　the　transducers　used　in　plates　has　been　extended　to　pipe　inspection　with　circumferential　arrays　because　of　the　similar　particle　displacement　patterns　of　some　modes　between　plate　and　pipe,　such　as　SH　and　torsional　modes.　Motivated　by　the　configuration　of　magnetostrictive　patch　transducer　(MPT),　in　which　a　planar　solenoid　array　(PSA)　coil　was　adopted　to　generate　SH　waves　in　plates,　we　proposed　a　MPTs　array　employing　a　modified　planar　solenoid　array　(MPSA)　coil,　i.e.　MPSA　coil-MPTs　array,　for　generating　and　receiving　the　torsional　mode　in　pipes.　The　configuration　of　the　MPSA　coil　modified　from　PSA　coil　is　suitable　to　be　arranged　on　the　pipe　surface　and　can　generate　high-power　waves.　In　the　suggested　configuration　of　MPT,　because　the　direction　of　the　actuating　dynamic　magnetic　field　produced　by　the　MPSA　coil　is　orthogonal　to　the　direction　of　the　static　magnetic　field　produced　by　the　permanent　magnets　in　the　magnetostrictive　patch,　the　shear　deformation　induced　by　the　magnetostriction　in　the　patch　will　be　delivered　to　the　pipe,　thus　generating　the　torsional　mode.　First,　it　was　experimentally　verified　that　the　fundamental　torsional　mode.　T(0,1),　could　be　effectively　generated　and　received　in　pipes　with　the　developed　MPSA　coil-MPTs　array.　Then,　we　studied　the　relationship　between　the　frequency　response　characteristic　of　the　developed　MPSA　coil-MPTs　array　and　the　interval　defined　by　the　distance　of　adjacent　solenoids　in　the　MPSA　coil.　Simultaneously,　the　circumferential　crack　defects　in　pipe　were　successfully　identified.　Finally,　the　performance　of　the　MPSA　coil-MPTs　array　was　compared　with　that　of　previous　meander　coil-MPTs　array.　The　comparison　results　demonstrated　that　the　developed　MPSA　coil-MPTs　array　could　enhance　the　power　of　the　torsional　mode.　(C)　2014　Elsevier　Ltd.　All　rights　reserved.
