Abstract: A phenomenological model to predict creep rupture times, based on material damage due to void growth and coalescence is presented. The model employs the Gurson-Tvergaard yield function together ...

Abstract: In this work, commercially pure aluminum sheets in both the as-received and annealed conditions are tested in uniaxial and biaxial tension. Biaxial stretching is performed in dies giving different ...

Abstract: A systematic approach is presented to estimate the roll separating force in bar rolling. This force is the product of the contact area between the rolled material and the roll pass, the mean ...

Abstract: Limiting strains during tube bulging have been investigated for long tubes subjected to an internal pressure together with an external axial force. A strain instability criterion which takes ...

Abstract: In this work central bursting in drawing and extrusion of metals is investigated. The analysis is based on a modified stress distribution within the die zone due to Shield (, 1955, J. Mech. ...
