Minimum Weight Design in Double-Layer Panels: Sheet Molding Compound versus Steel

Source

This paper deals with the use of structural optimization techniques to achieve weight reduction in automotive panels made from sheet molding compound2 (SMC) and steel Multiple stiffness criteria are imposed as performance requirements on the panels. Specifically, we consider the effect of changes in structural stiffness criteria as well as minimum gage and allowable depth constraints on the minimum weight design of double-layer panesl. Both SMC and steel designs are compared.
