The current study is aimed at improving the crashworthiness of a crash box in a lightweight passenger car, such that it becomes more energy absorbent in terms of frontal impacts. Numerical simulation aids them in cutting down testing time and overall cost endured by providing a reliable amount of insights into the process. According to NHTSA, a vehicle is rated based on these safety criteria, for which automobile manufacturers conduct a plethora of crash-related studies. The frontal impact test is the most primary form of crash test, which focuses on improving passenger's safety and comfort. Crash tests are conventional forms of non-destructive methods to validate the vehicle for its crashworthiness and compatibility based on different operating conditions. One such vital factor is crash safety, otherwise known as crashworthiness. * e-mail: manufacturers rely on rigorous testing and simulations to construct their vehicles durable and safe in all aspects.
