An experiment simulating the deformation that occurs in hot rolling, by rolling a small specimen of aluminium at room temperature with rough rolls, is described. A rectangular grid incorporated into the body of the specimen allows the determination of the mode of deformation that occurs under conditions of plane strain. The data are anlysed by a computerized method which presents the results in the form of a pattern of directions of maximum shear stress. The pattern obtained agrees substantially with a theoretical slip-line field of the type first proposed by Alexander.
