Stress-concentration factors have been determined photoelastically for shoulder fillets and grooves in plates subjected to tension and bending. The parameters were mainly outside the range of previously published work which is also critically examined.
The validity of Neuber's analysis for grooved plates is confirmed. The new results on shouldered plates provide a useful extension to Engineering Sciences Data Unit item no. 69020 for small values of r/d and values of D/d from 1.01 to 1.5, where r is the fillet radius, D is the greater width, and d the smaller width of the plate.
These results for plates may be applied to shouldered shafts without the incurring of serious error.
