Fast and Accurate Fatigue Crack Growth Analysis with the Boundary Cracklet Method

摘要

In this study, a simple crack growth emanating from a series of polygon shapedrnholes in an infinite plate is analysed by using the Boundary Cracklet Method (BCM)rnwhich has already proved that it is fast and accurate. The fatigue crack growth isrnassumed to follow Paris-Erdogan Law. Polygon shaped holes are modelled usingrnfour-sided regular polygons (square and rhombus) whose sides are created byrnstraight cracks in the subtle implementation of the method. The study is performedrnvia graphs and tables to demonstrate the ability of BCM in the analysis of fatiguerncrack growth for the given configurations.
