Abstract

The paper presents a calculation of the stress fields that arise in cylindrical steel rods of circular cross-section, in the case of the axisymmetric Pochhammer – Chree waves for the zero mode. The maximum tension and maximum shear on the surface of the rod and on its axis are calculated. Frequency ranges are obtained for which the maximum stresses on the rod axis are several times higher than on the surface.

Abstract

The ideal flow theory for pressure-dependent materials is used to calculate an ideal die for plane strain extrusion/drawing. In particular, the double slip and rotation and double shearing model are adopted. Comparison with the available ideal flow solution for pressure – independent material is made. It is shown that the die for pressure-dependent material is shorter than that for pressure-independent material. Moreover, the angle of internal friction has an effect of the distribution of contact pressure.
