Photoelastic investigation of stresses at an oblique hole in a thick flat plate under uniform uniaxial tension

Abstract

The magnitudes and positions of the principal stress indices at a series of isolated oblique holes in thick, wide plates subjected to uniaxial tension have been determined using the photoelastic frozen-stress technique. The model series covered nominal plate thickness to hole diameter ratios of 1.33, 2.0, and 3.0, hole obliquity angles of 0, 15, 30, 45, and 60 degrees, and applied load directions of 0, 30, 60, and 90 degrees relative to the major axis of the surface ellipse. The results are discussed in detail and compared with other independent values available in the literature.
