摘要
Calculation results to evaluate time variations of the stress intensity factor near the tip of the edge crack upon its stepwise growth are presented. The crack pop-in in a thick plate under tensile loading is shown to result in cyclic K1 variations with a period and amplitude that are dependent on the initial crack length, pop-in length and plate dimensions. Time-average K1 values correspond to those calculated for the stationary crack. © 2005 Springer Science + Business Media, Inc.
