Dual-plateau crashworthiness characteristics of star-shaped honeycombs with non-conventional semicircular ligaments

Key Points

• Crashworthiness significantly improves with dual-plateau characteristics, enhancing energy absorption during impact.
• The star-shaped honeycombs show notable energy absorption of up to 40% compared to conventional structures.
• Observational analysis of models with semicircular ligaments reveals enhanced structural integrity and resilience.
• Highlighting the potential for advanced materials in vehicle safety applications, this study prompts further exploration.
