Abstract:

Lug and groove connections are frequently found in structures where two components meet and loads are transmitted. These grooves usually have a nonsymmetric shape, i.e., the flank angle at the loaded face is different from that at the free face. While numerous data on stress concentrations for symmetric-shaped grooves for example, U- or V-shaped are available, very little information exists for nonsymmetric-shaped grooves. This report describes a photoelastic study on stress concentration in plates due to axial tension of loaded nonsymmetric-shaped grooves. Groove geometries as well as loading conditions are given. Maximum groove stresses were found and stress concentration factors were calculated. Also, parametric curves of stress concentration were obtained. A comparison was made between experimental results and those calculated by means of Heywoods equation.
