Multi-material solutions for the light weighting of electric and internal combustion engine (ICE) vehicles is an emerging trend to replace structural components made of steel/aluminum. Automotive chassis consists of structural members such as rails, posts and rockers, which form frames that need to meet stringent crashworthiness requirements such as frontal, side (IIHS & Pole) and rollover impacts. The high strength steel and aluminum used in these structures are often heavy and require several secondary steps to complete the frame. In the present paper, we discuss the design and optimization of multi-material hybrid rocker panel solutions to meet pole impact requirements and decrease weight with an emphasis on structural battery protection in electric vehicles. Rocker panel structures are situated at the bottom of the lateral edges of the vehicle and extend longitudinally along the length of the vehicle, between the front and rear wheels.
