Abstract
In this study, a 3D hybrid sampling moire method, which combines sampling moire method and finite element (FE) analysis in 3D model, is developed for evaluating the stress concentration of structures. Three-dimensional displacement distribution measured by the sampling moire method is compared with the analyzed result based on elastic FE analysis at assumptive boundary conditions. The optimum boundary conditions are determined by finding the minimum evaluation error between the displacement distributions obtained by experiment and FE analysis. Once the appropriate boundary conditions are determined, three-dimensional distribution of strain and stress, including the inner or occlusion parts, can be obtained by FE analysis for evaluation the stress concentration. The hybrid technique is useful to evaluate reliability of various actual structures in real phenomenon.
