Abstract

The paper reviews a series of experimental stress analysis methods using moire fringe and laser speckles. An analogy is drawn between the two groups of methods showing that moire methods are special cases of speckle methods. Difference between the two approaches are also pointed out. The experimental methods discussed include the analysis of plane stress and general three-dimensional problems, static and dynamic bending of plates, steady state vibration and transient stress problems.
