The　phase　field　method　(PFM)　by　means　of　regularization　fractures　has　become　a　promising　and　popular　method　for　complex　crack　propagation,　especially　in　geotechnical　applications.　Attractive　as　it　is,　a　challenge　exists　for　the　PFM　to　obtain　explicit　representation　of　cracks　and　jump　displacement　field　across　cracks　that　are　essential　and　crucial　for　some　applications,　e.g.,　hydraulic　fracturing,　leakage　problems,　and　contact　problems.　In　the　present　paper,　an　algorithm　in　which　the　values　of　phase　field　are　regarded　as　the　indicator　to　identify　crack　paths　is　proposed.　Then　physical　patches　are　cut　by　the　reconstructed　crack　paths　to　obtain　explicit　cracks　and　jump　displacement　field　in　the　context　of　the　numerical　manifold　method　(NMM).　The　numerical　examples　investigate　that　various　explicit　cracks,　including　a　straight　crack,　a　curve　crack,　the　branching　cracks,　and　the　merging　cracks,　predicted　by　the　proposed　method　are　in　good　agreement　with　the　literature.　Besides,　the　Sneddon＇s　example　verifies　that　the　discontinuous　displacement　field　across　explicit　cracks　is　in　line　with　the　closed　form　solution.　The　proposed　numerical　model　deserves　a　further　investigation.　(C)　2021　Elsevier　B.V.　All　rights　reserved.
