Intersection of Surface Flaws with Free Surfaces: An Experimental Study

Source

A series of frozen stress experiments was conducted on surface flaws of varying aspect ratios in finite-thickness plates in order to study the practical aspects of the well-known loss of the inverse square-root singularity when the flaw borders intersect the free surface. Optical data are converted into classical stress-intensity factors ignoring and accounting for the above-noted effect and compared with a well-established numerical result. Results are discussed regarding their usefulness to both the research and practicing engineer.
