There are lots of validations through CAE and test in the development of vehicle to satisfy customer needs in the automotive industry. Closure slam is one of these validation which is the situation when customer close the closure like as hood, side door and lift gate. In this paper, hood slam and lift gate slam are considered where the structure has notch at the impacted area. Generally, commercial CAE tool can calculate notch effect automatically considering geometric characteristic, but in some cases, this is not enough to predict correct fatigue life through analysis due to under estimated stress near notch area. Seegerheuler method was used for calculation of correct stress and strain at notch area, and this approach had showed very good correlation with physical test. Additionally, this correlated data can show us optimized design update through accurate fatigue life prediction.
