Stress intensity factors of various size single edge-cracked tension specimens: A review and new solutions

Non-dimensional geometric correction factor, beta, data for stress intensity factor, K, calculations are generated through finite element analyses and collected from the literature for axially loaded single-edge cracked plates with rotationally free and constrained loaded edges typically used in fatigue crack growth experiments. The solutions are valid for crack length-to-width ratio, alpha/W, in the range of 0.01 <= alpha/W <= 0.975 and plate height-to-width ratio, H/W, in the range of 0.8 <= H/W <= 10.0. Comparisons are made between the literature reported data and the present effort's results with generally satisfactory correlation. However, differences as large as 12.7% exist for short cracks in small H/W valued plates. (C) 2016 Elsevier Ltd. All rights reserved.
