Abstract

This paper describes the stress intensity factor for a semicircular surface crack embedded in a finite plate of cubic single crystals of Cu, Ni, Si, Al, and W, in consideration of anisotropy caused by the crystallographic texture. The correction factor FI of the stress intensity factor was calculated by means of the 3D finite-element method (FEM). The FI value depends on both the material and crystal direction. The relationships among the FI value and Young's modulus, shear modulus, and Poisson's ratio were discussed. A simple method of estimating the FI value for cubic single crystals was proposed by introducing a parameter which expresses the intensity of elastic anisotropy. The FI value can be estimated by this method in the range of elastic anisotropy between 1.00 and 3.20 for several crystal directions.
