Abstract
Summary: Two-dimensional photoelastic tests have been carried out on uni-axially loaded flat-plate specimens with two collinear edge slits, to investigate the effect of finite plate width on the elastic stress distribution. It was found that the effect of slitlength/ plate-width ratio on the elastic stress concentration at the end of the edge slit of lengthlwas virtually the same as that for a central slit of length2lin a plate of the same width, and could be adequately expressed by existing theories.
