In automotive industry there is increasing demand for higher quality exterior panels. Better functional properties and lower weight. The demand for weight reduction has led tothinner sheets, greater use of high strength steels and a change from steel to aluminum grades.This thickness reduction, which causes decrease in the dent resistance, promoted examination ofthe dent resistance against static and dynamic concentratedloads. This paper describes aninvestigation of the suitability of explicit dynamic FE analysis as a mean to determine thedynamic dent properties of the panel. This investigation is carried out on the body panel ofutility vehicle and covers two parts, in first experimental analysis is carried out on developed testrig, which is interfaced with the computer. This test rig measures deflection with accuracy of.001mm. The experimental results are then compared with the simulation results, which is thesecond part. Simulation is carried with non-linear transient dynamic explicit analysis usingAnsys -LSDyna software. The experimental results show great accuracy with simulation results. Theeffect of change in thickness and geometry of the existing fender is then studied with help ofsimulation technique. By considering the best possible option overall weight offender is reducedby 7.07 % by keeping the dent resistance of the panel constant
