Numerical simulation evaluates bow stress patterns during extreme sea ice ramming along the Northern Sea Route, suggesting structural safety baselines for icebreaker design.
Key Points
Bow stress patterns and structural deformation vary substantially across ramming speeds when icebreakers encounter extreme sea ice thickness along the route.
Numerical modeling in LS-DYNA evaluated ice-breaking dynamics across four representative Arctic sites selected from yearly extreme thickness statistics.
Structural evaluation against maritime regulations provides quantitative stress benchmarks to guide resilient icebreaker design for Northern Sea Route navigation.
