Photoelastic Analysis of Stresses around an Oblique Circular Hole

Abstract

The stress analysis near an oblique circular hole boundary in a plate subjected to tension is one of the important problems in collecting basic data for machine design. However, for various dimensions of plate widths, oblique angles and plate thicknesses, sufficient information on the stress-concentration due to the oblique hole boundary has not been presented. Accordingly, it is necessary to obtain sufficient data on the stress-concentration around the oblique hole by performing further systematic investigation. In the present paper, the stress distribution near the oblique hole boundary and the stress-concentration factor are measured in detail by using the photoelastic stress freezing method.
