Stress intensity factors for single edge cracks in rectangular sheets subjected to end rotations about the centerline 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 lengthwidth ratios of the sheet. Author
