Enhanced bendability in sheet metal produced by cladding a ductile layer
Abstract
The effect of cladding on the bendability of sheet metal is investigated numerically using the finite element method by employing the Gurson-Tvergaard-Needleman (GTN) model. The bendability and fracture strain increase significantly by cladding the sheet. In clad sheet metal, the development of the stress triaxiality in the region of the fracture slows down, thereby delaying the nucleation and growth of voids. In thin clad layers, the damage is …
