Early　detection　of　poor　interface　bonding　strength　for　the　explosive　clad　pipe　is　crucial　in　order　to　avoid　sudden　failure　and　even　catastrophic　accidents.　The　dynamic　response　characteristics　of　explosive　clad　pipe　are　investigated　to　explore　efficient　methods　for　identifying　the　bonding　strength　in　this　paper.　The　slender　explosive　clad　pipe　is　regarded　as　two　parallel　Bernoulli-Euler　beams　continuously　joined　by　a　virtual　Winkler-type　elastic　layer,　and　the　elastic　stiffness　is　capable　to　describe　the　bonding　strength.　Then,　motion　of　the　explosive　clad　pipe　system　is　described　by　a　homogeneous　set　of　two　partial　differential　equations.　The　classical　modal　expansion　method　is　employed　to　ascertain　dynamic　response　of　the　system　due　to　arbitrary　distributed　continuous　loads.　After　validation　of　the　proposed　approach　results　with　results　reported　by　well-known　reference,　the　effects　of　elastic　stiffness　on　the　forced　vibration　of　the　explosive　clad　pipe　system　are　investigated　in　the　case　of　concentrated　harmonic　excitation　force.　Numerical　results　demonstrate　that　vibration　characteristics　of　the　forced　transverse　vibration　are　sensitive　to　elastic　stiffness　of　the　system,　and　can　be　used　to　identify　the　bonding　strength　of　explosive　clad　pipe.　©　2018　IEEE.
