Kan, W. Blackburn] As a consequence of a fracture toughness testing program where several of the compact tension specimens were subsequently found to have fatigue pre-crack profiles invalidated by the criteria of British Standards BS5447, computations have been made of the stress intensity factor K I and the contour integral J for a sample of four invalid specimens to establish the error involved. A finite element analysis was carried out on models of the specimens, and the results were compared to those obtained for similar, but valid pre-crack profiles. A further comparison was also made of the K I values obtained by the finite element modelling and the analytical approach of BS5447. Kluwer Academic Publishers, 1992 Kan R.
