Abstract

In this study, the elastic-plastic deformation of a free-end cylinder with temperature dependent yield stress subjected to uniform internal heat generation is investigated. The cylinder is assumed to be radially constrained at the outer boundary by means of the external cladding. The analysis is based on Tresca's yield condition and the associated flow rule. The effect of the temperature dependence of yield stress on the expansion of plastic region and on the distribution of stress is displayed graphically.

Özet

Bu çalışmada, akma dayanımı sıcaklığa bağlı bir malzemeden yapılmış, uçları serbest ve düzgün iç ısı üretimi etkisindeki bir silindir için elastik-plastik deformasyon analizi yapılmıştır. Silindirin dışına geçirilmiş bir kılıf ile radyal doğrultuda dış yüzeyindeki deplasmanı engellenmiştir. Analiz sırasında Tresca akma şartı ve yardımcı akış kuralı kullanılmıştır. Silindir malzemesinin akma dayanımının sıcaklığa bağlı olmasının, plastik bölgenin ilerlemesine ve gerilme dağılımına olan etkisi grafiklerle gösterilmiştir.
