Abstract: Dimple sheet is formed using cold rolling or press braking process. Wider use of dimple sheet in various fields may create interest in the study of dimple sheet. This paper describes a numerical modeling approach and results into the mechanical property. A mechanical tensile test on plain sheet and dimpled sheet CR4 steel material were conducted for evaluation of numerical results. A finite element explicit dynamic analysis approach is used to simulate the tensile test. Tensile tests are carried out as per orthogonal array of Taguchi method. True stress–strain data obtained from tests were used to optimize the process parameters, this could correlate to the increase in the strength of the dimpled sheet as observed in experimental tests and simulations.. The process parameters of dimple forming such as dimple depth, dimple diameter and distance between dimples are analyze for strength of sheet on CR4 steel material. Design of experiments is implemented for to optimize process parameters by using a Taguchi method design. The effect of the process parameters on response have studied by means of main effect plots which are developed by SN ratio and optimum parameter is selected on the basis of signal to noise ratio.
