Factors of stress concentration for deep, sharp, and symmetrically arranged grooves and fillets in tension members have been determined photoelastically and are given in this report. Curves are given showing the distribution of the principal stresses on the section through the grooves. Complete isopachic patterns for several basic cases of grooved bars are included.
