This paper presents the effect of eccentric cracks on the behavior of stress intensity factors (SIF) of single edge crack in bi-material plates. According to literature, it is found that most of the research conducted previously more on central single edge crack and it is well understood. However, not many research conducted on the eccentric stress intensity factor of single edge crack in bi-material plates. In order to evaluate the SIFs of eccentric edge cracks, ANSYS finite element software is used to model plain strain single edge crack in a plate subjected mode I loadings. The present SIFs are then validated with the existing central crack and it is well agreed to each others. According to the present results, it is found that mode I SIFs decreased insignificantly and mode II SIFs decreased asymptotically when the crack situated away from the central line. As expected all types of SIFs increased when crack length is increased.

Riemann Hilbert Problem

Stress-intensity factors for single-edge cracks in rectangular sheets subjected to end rotations about the center line of the rectangle are investigated. The problem of the distribution of stress around the crack tip is reduced to the solution of a Riemann-Hilbert problem. Numerical results are presented for varying crack lengths and length/width ratios of the sheet.

Inclined Cracks

This paper presents numerical analysis of stress intensity factors (SIFs) of inclined cracks due to mechanical mismatches. According to literature survey, tremendous amounts of SIFs can be found elsewhere. However, the SIFs for inclined cracks are difficult to obtain especially when mechanical mismatch at the crack interface are considered. ANSYS finite element program is used to model the cracks embedded in plain strain plates. The cracks are oriented at the interface between two different materials and subjected to mode I tension loading. It is showed that when mechanical mismatches are introduced the mode I SIFs reduced and on the other hand mode II SIFs increased. When the cracks are inclined, the mode I SIFs diverged but it is not for mode II SIFs and gradually increased when compared with the normal cracks.
