Calculation of stress intensity factors by boundary element method based on erdogan fundamental solutions

The Erdogan fundamental solutions for infinitecracked plates are introduced in this paper. The spline fictitious boundaryelement method is then proposed and formulated for analysis of mode I andmixed mode (mode I and II) problems based on the above fundamentalsolutions. The proposed method is further applied to analyze certaincrack problems, in which the computation accuracy, convergence rate and theversatility of the method are demonstrated in details.
