Pagination or Media Count:
The prestrain effects produced under conditions of different stress states but identical strain states were correlated with the tensile fracture and flow properties of 2S-O aluminum plate. For prestrains of the same magnitude, a prestrain stress state of simple compression resulted in a higher retained tensile ductility than did a prestrain stress state of biaxial tension. A change in prestrain stress state from simple compression to biaxial tension influenced the shape of the fracture stress versus prestrain curve but did not affect the shape of the curves for yield strength versus prestrain.
