Abstract

The present work presents using scattered light technique for determination of 3D stress field. It is a generalization of the earlier introduced isodynes method, where by help of isodyne image and equilibrium equation stress field in the 2D case can be established. The 3D methods base on measurements of the intensity of the scattered light in some perpendicular to laser beam directions. It allow us to determine stress tensor but without hydrostatic component. However, this component can be obtained when two beams propagating in opposite directions interfere.
