  • 摘要:

    In the preceeding reports, the authors discussed on the several kinds of crack arrester model with application of two dimensional elasticity theory of cracked plate. Numerical calculations and some preliminary experiments showed that the brittle crack propagaion arrest could be explained by a relatively simple fracture mechanics criterion based on Kc-concept. In this report integral stiffener type arrester model is considered. An approximate calculation was made to see the effect of geometrical factors of the stiffener, such as its breadth and depth, on the stress intensity factor of the crack running perpendiculer to the stiffener. Some experimental checks were tried using the double tension with integral arrest stiffener model and the results showed a good agreement with the theoretical estimation. A further study on several other types of arrester is now in progress and the paper on it will be reported in near future.
