Bending stress distributions of plate beams having one circular hole of radius R, or two holes on one side in regard to their central lines, were studied under uniform bending moment. Analytical solutions were obtained by combining Suehiro's and Tuzi's stress functions, using polar co-ordinates, or Jeffery's function using bi-polar coordinates, and compared with the photo-elastic experimental results. Factors of stress concentration obtained anlytically and experimentally, agreed fairly with each other. Taking distance between the central line and the center of hole as m R, then the facter of stress concentration N_A at the farthest peripheral point from the central line was expressed approximately as N_A=3-1/(m+1), and N_B at the nearest point as N_B=3+1/(m-1). Point where the bending stress is zero, situated very near to the central line. (Received May 31, 1951)
