Abstract

This paper deals with the determination of stresses around a circular hole in a cantilevered wedge of uniform thickness subjected to end loading, using electrical resistance strain gauges. The authors have previously reported a similar investigation on a 45 wedge. The results obtained are compared with the theoretical analysis for an infinite perforated wedge given by Ling and Hsu. The stress concentration factors are calculated on the basis of nominal stress in the wedge at the hole boundary (using the theory for calculating stresses in a wedge without a hole). A maximum stress concentration factor of 3–2 was indicated for an end vertical load; and a maximum factor of 2 6 was indicated for an end horizontal load.
