In this paper, we developed a method to analyze of mechanical structures. The method is based on determination of phase difference of digital projection moiré fringes due to out-of-plane displacements or three dimensional profile of the sample. Buckling of glass/polyester composite column and bending deflection of aluminum beam has been studied by the technique. The image process session including generation and phase analysis of moiré fringes has all been done digitally and the results can lead to three dimensional information of the specimen surface. Simple equipment, fast data process, enormous amount of measured information from specimen, non-destructivity, capability to be used at high temperatures, and the ability of automated measurement for system health monitoring are the main advantages of the method.
Keywords: Digital moiré, Projection moiré, Non-destructed test, 3D profilometry, Out-of-plan deflection
