Abstract

Based on Tresca's yield condition and the associated flow rule, the stress distribution in the fully plasticized hub of a shrink fit rotating with supercritical angular speed is discussed. It is shown that the plasticized hub consists of two parts governed by different regimes of the yield condition. At the inwards moving border separating these parts, the image points in the stress plane migrate from one side-regime through the corner into the adjacent side-regime of the Tresca hexagon. The problem is solved in closed form.

Zusammenfassung

Untersucht wird die Spannungsverteilung in der vollplastizierten Nabe eines Querpreßverbandes, welcher mit überkritischer Winkelgeschwindigkeit rotiert. Zugrundegelegt ist die Trescasche Fließbedingung und die zugehörige Fließregel. Die plastizierte Nabe besteht aus zwei Bereichen, in denen verschiedene Regime der Fließbedingung maßgebend sind. An der sich nach innen bewegenden Grenze zwischen diesen Bereichen wandern die Spannungsbildpunkte in der Spannungsebene von einem Seitenregime durch die Ecke in das benachbarte Seitenregime des Tresca-Sechsecks. Die Lösung liegt in geschlossener Form vor.
