A　simplified　meshless　method　for　dynamic　crack　growth　is　presented.　The　method　uses　an　extrinsic　enrichment　based　on　a　local　partition　of　unity　concept.　The　crack　is　represented　by　a　set　of　crack　segments.　The　crack　segments　are　required　to　pass　through　the　entire　domain　of　influence　of　node.　They　are　introduced　when　the　maximum　principal　stress　exceeds　the　uniaxial　tensile　strength.　The　crack　segments　are　allowed　to　rotate　in　order　to　avoid　too　stiff　system　responses.　The　major　advantage　of　our　method　is　that　it　does　not　require　algorithms　to　track　the　crack　path.　(C)　2008　Elsevier　Ltd.　All　rights　reserved.
