Authors Abstract
Content
Among the various high strength steels available today, boron steels are finding increasing applications in bumper beams and other crash resistant structures, primarily for their high strength. However, to overcome the forming difficulty at room temperature and to achieve the microstructural changes needed for high strength, manufacturing of boron steel parts is done under hot forming conditions. In this study, the effect of three principal bumper design parameters, namely depth, thickness and corner radius on the formability of a hat section bumper beam was considered. Using a forming simulation program, 27 different combinations of these three design parameters were examined for forming limits, failure types and failure locations. The bumper beams were also examined for energy absorption in pendulum impact tests. Recommendations are made for the design of boron steel bumper beams based on both impact energy absorption and formability.
