Based on Tresca's yield criterion and the associated flow rule, the distribution of stress and displacement in the completely plasticized hub of a rotating shrink fit is studied. The hub material exhibits linear hardening. At the critical angular speed, a change in the Tresca regime takes place.

On the elastic-plastic shrink fit with supercritical interference Gamer, U; Müftü, Sinan (Wiley, 1990) Shrink fits with perfectly elastic-plastic hub material cannot be treated with the help of Tresca's yield criterion, if the ratio of outer and inner diameter as well as the interference exceed certain limits. For linear hardening material, however, a solution exists for all radii ratios. It is shown that, for small hardening, the material in the neighbourhood of the interface undergoes a twofold change of the yield condition.
The shrink fit consisting of elastic hollow shaft and nonlinearly hardening elastic-plastic hub Orcan, Y; GAMER, U (Springer Science and Business Media LLC, 1990-3) Based on Tresca's yield criterion and the flow rule associated to it, general expressions for stresses and displacement in a shrink fit consisting of elastic hollow inclusion and elastic-plastic hub with arbitrary nonlinear isotropic hardening are derived. For two specific hardening laws—one of Ludwik type and the other of Swift type—there follows the explicit determination of stresses and displacement together with numerical results.
The strain hardening rotating hollow shaft subject to a positive temperature gradient Eraslan, Ahmet Nedim; Mack, W. (Springer Science and Business Media LLC, 2007-11-01) Based on Tresca's yield criterion and the flow rule associated with it, the distribution of stress, strain and displacement in a linearly strain hardening elastic-plastic hollow shaft subject to a positive radial temperature gradient and monotonously increasing angular speed is investigated. Presupposing circular symmetry and plane strain conditions, the problem is accessible to an analytical treatment. It is found that - depending on the temperature difference between the outer and the inner surface - qual...
Stress distributions in elastic-plastic rotating disks with elliptical thickness profiles using Tresca and von Mises criteria Eraslan, Ahmet Nedim (Wiley, 2005-04-01) Analytical and numerical solutions for the elastic-plastic stress distribution in rotating variable thickness solid and annular disks are obtained under plane stress assumption. The thickness of the disk is assumed to vary radially in elliptic form which represents a wide range of continuously variable nonlinear cross-sectional profiles. Tresca's yield criterion and its associated flow rule are used to obtain analytical solutions for a linear hardening material. A computational model is developed to obtain ...
ON THE EXPANSION OF PLASTIC REGIONS IN THE ANNULAR PARTS OF A SHRINK FIT DURING ASSEMBLAGE ORCAN, Y; GAMER, U (Wiley, 1994-01-01) During assemblage of a shrink fit consisting of annular shaft and annular hub, partial oi complete plastic deformation of either part can occur. If a perfectly plastic annulars is about to be fully plasticized, the interface pressure and the elastic-plastic border radius of the other annulus, which mag harden isotropically in an arbitrary way, assume stationary values. In addition to that, the case of two simultaneously fully plasticized annuli of perfectly plastic behavior is studied
