With　the　widely　use　of　high-strength　steel　sheets　in　the　automotive　industry,　the　twist　springback　phenomenon　of　the　steel　sheets　under　multi-step　forming　conditions　has　received　extensive　attention.　In　this　work,　the　Dual　Phase　steel　DP500　is　taken　as　the　research　object　to　investigate　the　complex　non-linear　elastoplastic　behaviors　and　twist　springback　under　two-step　loading　paths.　The　large　specimen　with　a　pre-strain　of　4%　true　strain　in　rolling　direction　is　carried　out　on　a　large　tensile　testing　machine,　and　several　specific　blanks　are　extracted　from　it　at　different　directions　for　a　subsequent　P-channel　forming.　The　influence　of　twist　springback　associated　with　the　pre-strain　is　analyzed.　The　finite　element　model　based　on　the　non-linear　elastic　model　and　the　homogeneous　anisotropic　hardening　model　(HAH)　is　also　established　for　the　springback　prediction　and　stress　analysis.　The　results　indicate　that　the　pre-strain　has　a　considerable　impact　on　the　twist　springback.　The　non-linear　strain　path　changes　resulted　from　pre-straining　not　only　influence　the　residual　stress　but　also　affect　the　elastic　modulus　distribution.
