heal.abstract Image interference of a grating with line rulings of a density of 500 lines per inch and its shadow is used for the determination of the surface topography in plane-stress problems. The procedure consists in using a white or monochromatic collimated light beam to illuminate the model surface. This beam is obliquely incident to the model at a known angle. A reference master grating is attached to the surface of the model and the interference pattern of this grating and its shadow, produced by the oblique light beam, is photographed in a position normal to the model. Interference patterns before and after loading of the specimen allow the determination of isopachics, which are the lines of equal thickness. The method is applied to several illustrative examples. The results obtained by experimental analysis are in good agreement with the corresponding theoretical or other experimental solutions. en
