The present study provides an illustration of the use of holographic moiré interferometry in the mechanical evaluation of finger-jointed wood assemblies. Finger joints are critical strength-determining elements in glued laminated structural timber, and are finding an increasing use in construction and transportation industries. These joints are a source of potential structural weakness, and hence it is of utmost importance to test the functioning quality of these joints. The finger-jointed timbers are tested to failure. The key advantage of holographic moiré interferometry resides in its ability to display the real phenomena along with their degree of relative importance.
