Most crash studies focus on straight, head-on impacts. However, real accidents are rarely that simple. Many crashes happen at angles—known as oblique loading—which makes them more unpredictable and dangerous. This research specifically addresses that challenge by designing crash boxes that can perform well not just in direct impacts, but also in angled collisions. The innovation lies in using foam-filled structures. Inside the metal crash box, lightweight foam material—such as aluminum foam—is added. This foam acts like a shock absorber. During a crash, it compresses and helps absorb energy, reducing the force transmitted to the rest of the vehicle and its passengers. The researchers used advanced simulation tools and optimization techniques to test different designs. They analyzed how variables such as foam thickness, material distribution, and geometric configuration affect performance under angled impacts. The results show that foam-filled crash boxes significantly improve energy absorption and reduce peak forces, even in oblique crash scenarios. This research strongly supports Sustainable Development Goal (SDG) 3: Good Health and Well-being. Road traffic injuries are a major global concern, and improving vehicle safety is essential to reducing fatalities and serious injuries. By designing crash structures that perform better in real-world conditions, this study contributes directly to protecting human lives. There is also a broader impact. Electric vehicles are becoming more common as the world shifts toward cleaner energy. However, ensuring their safety is just as important as improving their environmental performance. Lightweight foam-filled designs help maintain efficiency while enhancing protection, making EVs both sustainable and safe. Another interesting aspect is the adaptability of this technology. The same design principles could be applied to other transportation systems, including conventional vehicles, trains, and even aerospace structures. This makes the research highly valuable across multiple industries. In simple terms, this study shows that safety innovation is not just about stronger materials—but smarter design. By understanding how crashes happen in the real world, engineers can develop solutions that protect people more effectively. As electric vehicles continue to shape the future of transportation, innovations like foam-filled crash boxes remind us that safety must evolve alongside technology. Because in the end, the goal is not just to move faster or cleaner—but to arrive safely, no matter the angle of impact.
