Abstract
ÖZET Bu çalışmada, anizotropik ortamlarda Eshelby, Read ve Shockley Metodu kullanılarak sonsuz uzunluklu doğru dislokasyonun birim uzunluğu başına elastik zorlanma enerjisi hesaplandı. Dislokasyon çizgisi ve Burgers vektörünün farklı yönelimlerine karşılık gelen kenar ve vida dislokasyonlarına ait enerji çarpanı bağıntıları türetildi. Su atmosfer basıncında hekzagonal yapıda kristalleşir. K faktörünün sayısal sonuçlan buzun taban düzlemindeki kayma dislokasyonu için hesaplandı. IV
ABSTRACT In this study, an expression for the elastic energy per unit length of a straight dislocation in a medium of anisotropy was calculated by using the Eshelby, Read and Schockley method. The energy factors (K) of the edge and screw components was derived for various orientations in the crystal of the dislocation line and its Burgers vector. Water crystallizes at atmospheric pressure to from ice Ih which belongs to hexagonal system. The numerical results of K factor were calculated for glide dislocation in the basal plane of hexagonal ice. V
