Abstract:

This report describes a three-dimensional photoelastic study on stresses in single-groove connections of the same material. Two groove profiles were investigated namely, the British standard buttress and the new profile. Boundary stresses, interior stresses, and contact stresses were determined. Shear-difference method was used and the procedure of the method was outlined. Appropriate checks for accuracy of the results were made. Heywoods empirical equation for calculating maximum fillet stress in loaded projections was reviewed. It was found that the British standard buttress is stronger than the new profile and that the Heywoods equation is not applicable in our problem. Further work on multi-groove connection is in progress.
