| Three-dimensional stress-strain analysis using multidirectional holographic interferometry and inversion methods is considered. The effect of refraction in the inhomogeneously deformed media on the fringe formation is demonstrated. Errors caused by internal refraction in the steep gradient region and a limited number of projections are estimated. Analytical, numerical and experimental results are compared. |
