A SCATTERED LIGHT PHOTOELASTIC METHOD FOR INVESTIGATING STRESSES IN AXIALLY SYMMETRIC PROBLEMS UNDER LIVE LOADS,
BOEING SCIENTIFIC RESEARCH LABS SEATTLE WASH
A scattered light photoelastic method for investigating stresses in axially symmetric problems at room temperature under live loads is described. Using this method, observations are required in only one plane. A scattered light polariscope using a Helium-Neon continuous wave gas laser as the light source was designed and assembled. The stresses in a simply-supported thick circular plate having a free span diameter of 3-in and a thickness of 1-in subjected to a concentrated load at the center were studied. Complete stress distributions were given for two concentric cylindrical sections with radii of 0.3 and 0.84 inches respectively. Author
