Numerical analysis was carried out for a set of seven candidate geometries, namely, triangle, rectangle, square, pentagon, octagon, cross, and the circle. In the analysis, all geometries were modeled with equal area of cross-section, and were compared to the rectangle; which served as the baseline. The results of the numerical analysis showed a 39-51 % improvement for the cross-shaped tube in comparison to the baseline rectangular tube. A theoretical and experimental study was then performed to characterize crushing behavior and energy absorption capacity of the cross-shaped tube. Comparisons were made among the different approaches used in this study, and the results show good agreement with each other. There was approximately 6 % difference between the theoretical and experimental approaches, approximately 7 % difference between the theoretical and the numerical approaches and 0.8 % difference between the numerical and experimental approaches. The results of this study can be used to design support structures to improve protection on impact, such as the front rails in the chassis of an automobile. 2014-09-23 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1407938652 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1407938652 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
