Abstract
Distributions of stresses in an infinite strip of finite breadth under tension and containing two pairs of equal semicircular notches placed symmetrically on the edges are studied theoretically. The state of decreasing of stress concentration is studied and compared with those corrected by M. Isida or newly determined by the author in their calculations as the reliable results of Ling’s problem of an infinite strip of finite breadth under tension and containing two semicircular notches placed symmetrically on the edges.
