An annealed sheet of AISI 1040 steel (0.85 mm thick and with in-plane isotropy) was tested in uniaxial tension until the onset of necking, to determine its formability. The initial specimen’s length and width were 20 and 2 cm, respectively. At the onset of necking, the length and width were 25 and 1.7 cm, respectively.
Â
(a) Determine the ratio between the through-thickness and the in-plane yield stress, assuming that R does not vary with strain.
(b) Draw the flow locus of this sheet, assuming that σy(1,2) = 180 MN/m
