F.5 COMPARISON OF GROOVED
AND NON-GROOVED CASES
The two cases of chain tensioued over 8 curved surface with a groove can be analyzed by the stress
equalions given in the preceding section by replacing al2 by a. Also, recall that for the case of
the upright IIJlk supported at the bottom of the groove, the surface diameter D must be defined
as the radius to the bottom of the groove. Figure F7 shows lbe non-dimensional Slress parameler

- plotted for these two cases, together with tbe noo-grooved surface case for {3 = 25°_
pAs reported by Buckle, the two grooved surface cases were analyzed by Lloyds Register of Shipping.
The analysis was done for stud-link chain with a finite-element technique. The inter-link angle a
