Abstract

A computational model is developed to investigate elastic stress distribution in variable thickness fins subjected to heating or both heating and centrifugation. The model is based on a realistic conduction-convection mechanism. Temperature dependency of modulus of elasticity, coefficient of thermal expansion, thermal conductivity and uniaxial yield limit of the fin material is taken into account. Making use of von Mises yield criterion, elastic limit heat load is calculated for both constant property and temperature dependency of material.

Özet

Isı yükü veya hem ısı yükü hem de merkezkaç kuvvet etkisindeki değişken kalınlıklı içi boş uzantılı yüzeylerde elastik gerilme dağılımlarını incelemek için bir sayısal hesaplama modeli geliştirilmiştir. Bu model, gerçekçi bir ısı iletim-taşınım prensibine dayanmaktadır. Kanat malzemesinin elastisite modülü, ısıl genleşme katsayısı, ısı iletim katsayısı ve akma gerilmesi değerlerinin sıcaklıkla değiştiği göz önüne alınmıştır. Von Mises akma kriteri kullanılarak, elastik limit ısı yükü malzeme özelliklerinin sabit olduğu durum ile sıcaklığın fonksiyonu olduğu durum için hesaplanmıştır.
