Abstract

Based on Tresca s yield criterion and its associated flow rule, the elastic-plastic deformation of a centrally heated composite cylinder with fixed ends is investigated by considering the influence of geometric parameters as well as material properties such as yield strength, modulus of elasticity, Poisson s ratio, coefficient of thermal conduction and thermal expansion. In the study, stress, strain and displacement distributions in the composite cylinder made of elastic-perfectly plastic material are derived. Stress distribution and evolution of plastic regions in the composite are presented for different levels of heat generation in the core.

Özet

Tresca akma kriteri ve birleşik akış kuralına dayanarak, iki ucu sabit, ortasından ısıtılan kompozit bir silindirin elastik-plastik deformasyonu, sadece geometrik parametrelerin etkisi değil aynı zamanda akma dayanımı, elastisite modülü, Poisson oranı, ısıl iletkenlik ve ısıl genleşme katsayıları gibi malzeme özelliklerinin de etkisi dikkate alınarak incelenmiştir. Çalışmada, elastik-mükemmel plastik malzemeden yapılmış bu kompozit silindirdeki gerilme, gerinim ve deplasman dağılımları elde edilmiştir. İçteki silindirde artan ısı üretimine göre değişen gerilme dağılımı ve plastik bölgelerin gelişimi grafiklerle gösterilmiştir.
