다국어 초록 (Multilingual Abstract)

There is a rising in environmental issues over the world. Therefore, Automobile-rated manufacturers have made all efforts to cut the emission of greenhouse gas. As a part of the effort, they are trying to reduce the weight of vehicle. There are some methods to reduce the weight of automobile. One is to replace heavy steel with light metal such as aluminum alloys or magnesium alloys etc. The other is to use high strength steels in order to reduce the thickness of the steel plate as thin as possible. However, both of them have some disadvantages. The price of the aluminum alloys or magnesium alloys is quiet expensive and high strength steels have a poor formability and high spring-back. In this study, the product development is bonded steel with different materials, not all-in-one steel produced at home and abroad. The purpose of center pillar study is to understand the dynamic characteristics of bonded-steel with different materials in order to protect the people inducing collapse behavior stably when the car was dented on the side by using lower-hardness materials of bottom parts and upper-hardness materials of top parts by the weld line of laser TWB (Tailor Weld Blanks)
