Study of Parameters that Affect Body Panel Performance Predictions 910289

Predictions of stiffness, denting energy, and critical buckling loads are integral parts of body panel structural design. The accuracy of these predictions depends upon the method used to simulate field conditions typically imposed upon the panel in service. This paper describes a study conducted to correlate the effects of different supports or boundary conditions and loading methods on the actual panel performance measurements. Specifically, panel stiffness and oil canning load measurements were experimentally made and compared under two different support conditions and indentor geometries. Conclusions are drawn with respect to each of these parameters to offer further insight into better predictions of panel performance during the design phase.
