A CTOD-Based Mixed-Mode Fracture Criterion
1999This paper presents a mixed-mode fracture criterion that uses the crack-tip opening displacement (CTOD) at a fixed distance behind the crack tip as the fracture parameter. This criterion is developed based on a detailed analysis of crack kinking in arbitrary directions. In essence, the proposed criterion states that crack growth occurs when the current

Development and validation of a low-cost CTOD procedure
2013A low-cost variation of CTOD testing is proposed. This variation follows BS7448, but has several nonstandard deviations, including:• Using a fixed notch width of 0.5 mm.• Using fatigue pre-cracks that are shorter than normal requirements to save the associated expense.• Using Single Edge Notched 3-point Bending (SENB) specimens with cross sections that
