Global warming crisis forces governments to act restrict rules to subside emission of greenhouse gases. Aluminum has been increasingly applied in different aeronautical and automotive industries thank to its light weight and high stiffness to weight ratio. Aluminum sheets used as outer panel of different machines like automobiles need to satisfy different standards like dent resistance. Dent resistance is a quality criterion for automotive body panels which should be considered in design. In this paper dent resistance of aluminum sheets is investigated using Finite Element Method and effective parameters are analyzed. Finally the combination of optimum parameters to maximize dent resistance is introduced.
