| Abstract | The stress concentration factors at butt joints in six-ply laminated lumber were determined experimentally. Concentration factors for a uniform tensile stress were found for a joint at each of three possible locations. Four experimental techniques were used and evaluated on actual wood specimens: strain gages, brittle lacquer, moiré grids, and photoelastic coatings. A model of the laminated section was constructed from a transparent photoelastic material and analyzed to determine the stress concentration factors along specific lines of interest. Agreement exists among the actual specimens, the model, and two theoretical solutions. At a given stress, the region of influence of the discontinuity on the stress distribution in the wood sample was determined. |
