Measurements of Mixed-Mode Crack Surface Displacements and Comparison With TheorySource: Journal of Applied Mechanics:;1980:;volume( 047 ):;issue: 003::page 557DOI: 10.1115/1.3153731Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of a finite-width tension specimen containing a crack oriented at various angles to the load axis is attacked from experimental and theoretical viewpoints. Displacements of an electro-machined slot, 12.5 mm long and oriented at angles of 0°, 15°, 30°, 45°, 60°, and 75°, are measured using a laser-based in-plane measuring technique. Various width specimens, ranging from a crack-length/width ratio of 0.167 to 0.794, are tested. A boundary-integral equation method is extended to deal with the presence of a sharp crack. Agreement between the two approaches is generally good except near the tips of the cracks.
