Abstract: Analytical expressions are derived for the required front pull for wire drawing, as well as the back push for extrusion. The effect of each of the process variables on these forces is presented ...

Abstract: This work is a direct extension of reference [3]. There the problem was treated with the assumption that the cone angle was small. Here this limitation exists no more. The operations of wire ...

Abstract: The operation of cold-strip rolling is treated under the assumption of “Mises” material. A lower upper bound on energy consumption is computed. Then, assuming constant shear between strip and ...

Abstract: This paper investigates an upper bound approach to plane strain deformation of a rigid, perfectly plastic material. In this approach the deformation region is divided into a finite number of ...

Abstract: Following Part I which investigated an upper bound approach to plane strain deformation of a rigid, perfectly plastic material, this Part II considers the same approach as applied to actual ...

Abstract: The boundaries of the plastic zone in radial flow through conical converging dies are analyzed. The assumed boundaries are generalized, so that their shape and location are functions of the ...

Abstract: The deformability of brittle composites, including a fiber-reinforced material, and the effect of plastic deformation on the tensile strength of such materials is investigated. The materials of ...
