| Abstract |
Localized neck in a sheet is assumed to occur by localized shear deformation on the plane where pure shear condition is attained. The three dimensional stress state of the incipient shear plane is determined from the stress transformation. The stress transformation gives the geometry of the slip plane and therefore approximates the shape of the localized neck. |
