Extract

In Part I the analysis was given of a circular hole (radius a) reinforced by a compact ring symmetrically placed either side of the shell skin which was assumed to be attached to the ring at its shear centre and centroid. The shell radius/thickness ratio (R/t) was assumed not to be large enough for non-linear effects to be significant.
