Validation of R6 Defect Assessment Methodology Using Experiments on Plates and Pipes with Surface Cracks

Source

Plates and pipes with surface cracks were loaded to a level at which a definite amount of stable crack growth was achieved. Nominal stresses necessary for stable crack extension in depth direction equal to that observed on fracture surfaces were calculated and compared to nominal stresses in experiments. Option 2 of the R6 supplied closer agreement with experiment than Option 1. All results calculated with Option 1 were conservative.
