Paper online: An improved semi-analytical solution for stress at round-tip notches (Engineering Fracture Mechanics)
Liu, M., Gan, Y., Hanaor, D., Liu, B., and Chen, C. (2015) An improved semi-analytical solution for stress at round-tip notches. Engineering Fracture Mechanics, 149, 134-142. [DOI] Abstract: In order to investigate the brittle failure of key-hole-notched components, the stress distribution at notch tips is studied numerically and theoretically. A semi-analytical formula is developed for the maximum notch-tip-stress, incorporating crack-tip-blunting,…
