RİJİD BİR KILIF İÇİNE YERLEŞTİRİLMİŞ AKMA DAYANIMI SICAKLIĞA BAĞLI BİR MALZEMEDEN YAPILMIŞ SİLİNDİRDE ELASTİK-PLASTİK GERİLME ANALİZİ
Abstract
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.
