Development of sample-scale shear bands during necking of ferrite-austenite sheet

This study is a quantitative, experimental study of development of shear band formation during plane strain extension of ferrite-austenite sheet. The position of aligned austenite islands was used to measure internal shape change throughout the development of flow localization to sheet failure. Through-thickness shearing flow and rotation of material by an angle φ develop during nonuniform thinning in order to maintain compatibility between...
