Some Three-Dimensional Aspects of Subcritical Flaw Growth as Measured in a Transparent Polymeric Material


After briefly reviewing an experimental optical technique for estimating crack shapes and corresponding stress intensity factor distributions in three-dimensional cracked body problems, this paper lists some basic observations on the three-dimensional aspects of subcritical flaw growth and supports them by citing results from application of the experimental method. Restrictions of the method are listed. It is concluded that, within the restrictions, the method is useful in supporting numerical analysis.
