Extract

An outline is given of a combined photoelastic and fatigue programme of work on single-pin double-strap joints; the stress concentration factors obtained from photoelastic tests are to be correlated with the results from a parallel series of metal fatiguetests on geometrically similar specimens. The form and dimensions for a photoelastic specimen suitable for this work are given. Further results will be published as the work proceeds. This Note outlines a programme of work recently initiated by the Royal Aeronautical Society, and now being done under Ministry of Supply contract, in connection with the fatigue strength of bolted joints.
