FEM Simulation of Bending Formability for Laminate Steel/Resin/Steel Lightweight Composite Sheet
FEM Simulation of Bending Formability for Laminate Steel／Resin／Steel Lightweight Composite Sheet

The ANSYS simulation software was used to analyze the bending formability of laminate steel/resin/steel lightweight composite sheet. The skin steel at external side produces relative slipping-off change during the bending due to its composite structure. The internal stress strain states, materials effect tools parameters and intermediate layer resin of lightweight sheet on slipping-off change were analyzed. The spring back and shear stress state after bending have also been discussed.
