Yanal izotropik fiber kompozit çubuklarda burulma yüklemeleri için yeni formda kayma modülü tanımlamaları

Bu çalışma, ilk olarak homojen olmayan fiber kompozit malzemeler üzerinde uygulanmakta olan burulma yüklemeleri altındaki çubuklara ait kayma modülü elastisite modelleri ve modellerin aralarındaki farklılıkların araştırılmasını içermektedir. İkinci olarak, kayma modülü tanımlamasının yanal izotrop malzemeler için yeni formda oluşturulması ele alınmıştır. Literatürde, değişik kesitlere sahip çubuklar için kısaca verilen iki boyutlu G(x, y) kayma modülü formülasyonları, yeniden oluşturulmuştur. Yeni bir form olarak, yanal izotropiye sahip fiber kompozit malzemeler için onbir bağımsız elastik sabite sahip kayma modülünün en genel tanımlaması yapılmıştır. Tanımlamaları yapılan bu yeni modelde kayma modülü, denklemler sistemi formunda oluşturulmuştur.

The new formed shear modulus formulations for the transversely isotropic fiber composite bars under torsion loading

This study first includes the researches about the elasticity models for nonhomogeneous fiber composites under torsional loading and the differences between them. Secondly, constitution of the new formed shear modulus definition was held on for the transversely isotropic materials. In literature, the given two dimensional G(x, y) shear modulus brief formulations about various cross sectional bars were derived again. As a new model, the most general definition which has eleven independent elastic constants for the transversely isotropic fiber composite material was generated. In this new form in which the definitions were given, shear modulus was defined in the form of the system of equations.
