Stress Intensity Factor of an Edge Interface Crack in a Bonded Semi-Infinite Plate

Effect of arbitrary bi‐material combination and bending loading conditions on stress intensity factors of an edge interface crack

“…In general, D(a,b,l) is expected to have several zeros in 0 , Re(l) , 1. The values of l for arbitrary material composite parameters (a,b) were computed in the authors' previous research (Noda et al, 2010;Lan et al, 2011b).…”

“…Treifi et al (2008Treifi et al ( , 2009 computed the SIFs for different configurations of cracked/notched plates subjected to in-plane shear and bending loading conditions by the fractal-like finite element method. Noda et al (2010) investigated the SIFs of the single-edge interface cracks in bonded dissimilar half-planes and finite bonded strips subjected to remote tension, and proposed a powerful empirical function for computing the SIFs of arbitrary material combinations and crack lengths. Then, Lan et al (2011a, b) discussed the effect of the material combinations and the relative crack lengths to the SIFs of a single edge cracked bonded strip subjected tensile loading conditions.…”

“…The SIFs of interface crack under bending condition will be computed for arbitrary material combinations and relative crack lengths. Then, the computed results will be compared with those for the tensile loading conditions which were published previously (Noda et al, 2010). Furthermore, empirical functions will also be proposed for the bending loading conditions in this paper.…”

Stress intensity factor for small edge crack in interfacial singularity region

“…Noda et al [5,6] showed the accurate method to analyze the intensity of the singular stress at the interface edge by using the stress ratio at the interface edge calculated by the finite element method. Moreover, Noda et al [7][8][9][10] reported that the stress intensity factor of the small interface crack in bonded materials, as well as the intensity of the singular stress at the interface corner, is effective for evaluating the adhesive strength.…”

Effects of resin thickness on the stress intensity factors of edge-cracked adhesive joints

“…Then, Oda et al [2] extended this method to analyze the interface crack problems by making the singular terms the same for the reference and target unknown problems. In the previous studies [3][4][5], we solved the SIFs of several edge interface cracks in bi-material bonded strips for arbitrary material combinations. These pioneering work provide a convenient manner to obtain the SIFs of the interface crack problems.…”
