Abstract
Yerel eğrilikli lifler içeren tek yönlü lifli kompozitlerde gerilme yayılımının belirlenmesi için, parçalı homojen cisim modeli çerçevesinde elastisite teorisinin üç-boyutlu geometrik nonlineer kesin denklemleri kullanılarak geliştirilen yöntem, lif ile matris arasında sabit kalınlıklı bir sargının olması durumuna geliştirilmiş ve lif boyunca yapılan tek yönlü yükleme altında lif, geçiş malzemesi ve matris malzemelerinin temas yüzeylerinde oluşan nomıal gerilmelerin araştırılmasında, lifler arasındaki etkileşimin ihmal edildiği durum için, kullanılmıştır. Geometrik nonlineeritenin bu gerilme değerlerine etkileri incelenmiş ve bunlarla ilgili çok sayıda sayısal sonuçlar verilmiştir.
İn the framework of the piecewise homogeneous body model with the üşe of the threedimensional geometrically nonlinear exact equations of the theory of elasticity, the method developed for the determination of the stress distribution in the unidirectional fibrous composites with locally curved fibres is üşed to investigate normal stresses acting along the fibers for the case where there exists the bond covering cylinder with constant thickness between fiber and matrix materials are considered The case for which the interaction between the fibres is not taken into account is studied. The numerous numerical results related to the stress distribution in considered body and the influence of geometrical nonlinearity to this distribution are obtained and interpreted.
