| Abstract: | The scattered-light photoelastic technique was utilized to determine Mode I stress-intensity factors associated with a semi-elliptical
surface flaw in a plate subjected to cylindrical bending. Stress-intensity factors were experimentally determined for the
point of maximum flaw penetration and the point of intersection of the flaw border with the free surface of the plate. Experimental
results compare favorably with those obtained in a three-dimensional finite-element analysis. |
