This　work　aims　to　handle　the　challenging　issues　including　numerical　instability,　contact,　crack　formation,　etc.　when　simulating　impacting　failure　problems.　The　proposed　approach　introduces　an　extended　non-ordinary　state-based　peridynamic　(NOSB-PD)　model　with　an　enhanced　hourglass　force　formulation,　integrated　with　a　point-to-volume　discrete　(PTVD)　contact　model　to　describe　the　interaction　between　metal　materials.　The　research　highlights　the　effectiveness　of　this　new　model　in　preventing　numerical　oscillations　and　mitigating　excessive　system　stiffness　by　incorporating　damage　effects　into　the　hourglass　force.　Numerical　examples　demonstrate　that　the　proposed　model　effectively　suppresses　zero-energy　modes,　avoids　system　over-stiffness　caused　by　hourglass　forces　in　damage-related　problems,　and　provides　a　PTVD　contact　model　compatible　with　peridynamics　for　addressing　metallic　impact　scenarios.　The　extend　peridynamic　model　can　accurately　characterize　metallic　impact　phenomena　and　demonstrates　predictive　capability　for　ballistic　limits　in　metallic　impacts,　suggesting　potential　applications　in　the　impact　analysis　of　ship　structures.　This　work　offers　a　contribution　by　improving　the　numerical　stability　and　accuracy　of　metal　impact　simulations.　©　2025　Elsevier　Ltd
