ILLUSTRATIONS OF TWO SIMPLE METHODS OF DETERMINING STRESS INTENSITY FACTORS FROM: (A) STRESS CONCENTRATIONS AND (B) STRESS DISTRIBUTIONS

Illustrative examples of two methods of determining approximate stress intensity factors from (a) stress concentration factors and (b) from stress distributions are presented. In the first case several example problems are presented whereby stress intensity factors are obtained from known stress concentration factor data. These illustrative problems include data obtained from both closed form and experimental solutions. The results of this method are compared to a well-known, accurate analysis, and guidelines regarding such usage are presented. In the second case several approximate methods of determining stress intensity factors utilizing stress distributions available in the literature are presented to the reader. Example problems are illustrated and compared to more accurate results when available. Estimates of the accuracy and limited guidance on the usage of such methods are given.
