Abstract

A wide range K_I solution has been developed for an eccentrically cracked middle tension specimen with clamped ends. In the derivation of the K_I solution, an equivalent model was developed; weight functions for eccentric cracks in a finite-width strip were utilized, with approximate closed form K_I and plate-end displacement solutions obtained. Good agreements between the approximate solutions and corresponding FEM results were observed over a wide range of eccentricities and crack lengths. The accuracy of the K_I solution was analyzed under different aspect ratio conditions, with the applicability of the approximate solutions given. The equivalent model was also discussed.
