Abstract or Summary
  • The merits of the photoelastic coating technique as applied to wood were evaluated. Comparative tests were made on 12 nominal two-by-four Douglas Fir boards. The object of these tests was to determine the limitations of this technique, such as accuracy and complexity of experimental procedure. Correlation of the experimental results was achieved by determining the modulus of elasticity for each board from load-deflection measurements, (1) at midpoint loading, (2) at third-point loading, (3) from strain gage readings, and (4) from photoelastic coating data. A linear regression analysis was used to find 90% and 95% confidence intervals of accuracy for the photoelastic data. As an application, the coating technique was used to investigate the stress distribution around butt joints in six-ply laminated beams.
