Analysis of fracture behavior and stress-strain distribution of martensite/austenite multilayered metallic sheet

► Multilayered metallic sheet is made by the lamination of brittle layer and ductile layer. ► Ductility of brittle layer increases by the suppression stress of ductile layer. ► The stress gradient between layers becomes similar in the fracture area. ► Void which is in the type of ductile fracture is observed in brittle layer. ► The fracture stain increased when each layer was thin.
