Abstract
A 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 are b=10 by w=20 mm, independent of material thickness. • Use of crosshead measured displacements in lieu of secondary displacement sensors. • Fast testing, which includes a time to maximum load of 1-2 seconds. Each deviation is justified with analysis, simulation, and/or testing. The proposed CTOD variation is then demonstrated on 25 mm thick Weldox 700E
