摘      要：The increasing applications of new materials such as high strength low alloy (HSAL) steels and aluminum alloy sheets have lead to greater focus on the surface deflections of auto body panels in the automobile industry in recent *** finite element models of cylindrical shallow shell that can represent auto body panels are *** simulations of forming and unloading of cylindrical shallow shell are carried *** a measurement and evaluation method of the surface deflection is *** simulations of surface deflections with various blank homing forces (BHF) show great agreement with the experi- mental *** influence laws of sheet thickness and material properties such as yield strengthσs,strain-hardening exponent n,anisotropy parameter r and strength coefficient k on the surface deflection are achieved by simulations,which give a basic refer- ence for controlling surface deflections.
