Abstract
A two-dimensional photoelastic study was made of the stress-concentration factor,k, in a statically loaded tensile strip of widthW, with a central circular hole of diameterD, to determine the value ofk asD/W→1. Here,\(k = \sigma _{\max } /\sigma _{nom}\) where\(\sigma _{\max }\) is the maximum stress at the hole and\(\sigma _{nom}\) is the nominal or average stress on the net cross-sectional area. Eight stress-concentration experiments were performed for 0.50≤D/W≤0.99, and it was found thatk→2 asD/W→1.
