Abstract
An optical interferometric nondestructive evaluation technique is introduced. Based on electronic speckle-pattern interferometry and a recent theory of plastic deformation, this technique is capable of visualizing stress concentration and predicting the location and timing of the failure of the object. The operation of the technique is demonstrated for tensile analyses of aluminum alloy samples.
