Interaction a between a Thin Elastic Stiffener and a Crack in an Anisotropic Half Space under Longitudinal Shear

抄録

This paper deals with the interaction between a thin elastic stiffener of finite length and an internal crack in an anisotropic half space under longitudinal shear. The problem is solved by the singular point method. Replacing the crack and the stiffener with continuous distributions of screw dislocations and concentrated forces, respectively, we obtain a set of singular integral equations. In order to clarify the influences of anisotropy of the matrix, physical properties of the stiffener, and the geometrical parameters of crack arrangement on the stress intensity factor at the tips of the crack, numerical calculations were performed. The results are shown in figures.
