It is well known that the most difficult and laborious problems in photoelastic stress analysis are determination of principal stress direction and assignment of fringe order over the whole area of a specimen. In a series of studies reported previously, however, the authors successfully proposed a new method for the whole-area analysis in two-dimensional photoelasticity based upon a concept of structure-driven-type image processing. This paper describes a newly developed method for auto-matic drawing of isostatics, i. e., stress trajectories, and separation of principal stress with a differential geometry method using isoclinic and isochromatic data obtained by the whole-area analysis mentioned above. Applicability of the method is investigated by comparison of the results obtained for both theoretical and experimental data.
