抄録

The photoelastic freezing method is applied to obtain the maximum stress in a plate under tension, having a circular hole reinforced by a stiffening ring. Araldite B is used for the photoelastic material and the stiffening ring is bonded to the hole cut in the plate. The plane of slice in the ring is taken parallel to the plane of plate. The difference method is used to investigate the variation of fringe intensity arising by slicing off the materials in the ring. The maximum stress at the boundary of the reinforced hole is given for the various thicknesses of stiffening rings and the optimum strength condition for the circular hole with a stiffening ring is discussed.
