2. A circle grid analysis of a vehicle front fender panel resulted in the strain map (%) shown below. The fender is made of a HSLA 0.50 mm steel panel. a. Draw the forming limit diagram (FLD) and indicate the location of the five strain measurements shown in the fender strain map, using the steel FLD sketch. b. Based on the FLD, indicate if any of the strain - measurement locations might fail. c. Describe the deformation mechanisms for each strain measurement location. d. Based on your FLD and the deformation map, comment on this formability practice, and suggest improvements (if any), to solve any possible problems. e. Note: any improvements suggested should utilize the same steel grade. f. On your FLD, draw or indicate the line that represents zero change in the steel panel thickness (i.e. zero strain in the panel thickness). II (-6, 12) IV (+22, 0) (10, 25) II V (15, 15) (-15, 15) 2.
