Abstract：Cohesiveinterface elementsareintroducedtosimulateinter-layerdelamInationacording tothe3Dcontinuous damageconstitutivetheoryofcompositelaminates.Combined withthe3DHashin failurecriterion，a Vumatsubroutineis writen to conduct parameterized research on high speedimpact of composite curved plates.The results show that under high speed impactoftheprojectile，thetensiledamageareaofthematrix decreasesfirstandthen increasesalong thethicknessdirection. When the impact velocity is greater than 115ms ，with the increase of impact velocity，the remainingvelocity approximately increaseslinearly，andthetensiledamageofthematrixfirstincreases，thendecreases，andfinallstabilizes.Astheincident angleincreases，theresidualvelocityof theprojectilegraduallydecreases，andafterpassingthroughthecurvedplate，the projectilesatitudeundergoescounterclockwisedeviation.Thelargertheincidentangle，themoreobvious thedeviation，andthe curved plate presents a front concave hole and rear bulging shape.
