Mma. Wahab et G. Deroeck, A FINITE-ELEMENT SOLUTION FOR ELLIPTIC CRACKS USING THE ICCI METHOD, Engineering fracture mechanics, 53(4), 1996, pp. 519-526
In one of our recent publications, a formula for the computation of th
e strain energy release rate from 3-D singularity finite elements was
derived based on the Irwin's Crack Closure Integral (ICCI) method. In
this paper, the stress intensity factors of embedded elliptical and se
mi-elliptical surface cracks in a finite thickness plate subjected to
tension are calculated using this formula. Comparisons between the num
erical results obtained using the formula and those from the literatur
e showed that the proposed technique yields accurate stress intensity
factors.
