The mounting bracket considered in the study is a product specifically designed and manufactured for a converted electric vehicle and failed during conventional operation of the vehicle. Thus, design improvement/revision (redesign) on the bracket geometry was investigated.

Thus, design improvement/revision (redesign) on the bracket geometry was investigated.
