    Abstract
    Cars are an important means of transportation; however, there are many cases wherein car accidents
    cause physical or material danger and damage. Although cars provide advantages such as
    convenience and quickness, car occupants are exposed to dangers, and unexpected accidents can
    occur because of the lack of cognition of the driver or the fault of another vehicle. A car-to-car
    accident is categorized into frontal, rear, and side crashes. Frontal, rear, and side crash tests are
    conducted as defined by the regulations of each country. In South Korea, a crash test is conducted,
    and the results are released under the KNCAP regulations; Europe, United States, and China also
    perform crash tests and assessments according to their regulations. If the crash test and assessment are
    conducted using an actual car, a considerable amount of time, space, and costs are required.
    Therefore, it is preferred to conduct the test and assessment using finite element analysis, which yields
    similar results to the actual car test while saving time, cost, and space. To this end, the characteristics
    and assessment of the car crash test were investigated using finite element analysis in this study.
