The use of optically isolated layers within a complex three‐dimensional model permits a photoelastic analysis in their planes at room temperatures. A programme was undertaken to determine experimentally the state of stress in, and the structural behaviour of a portion of the aft bulkhead of an Fill aircraft in order to improve the fatigue life of the component. Information obtained about its behaviour under load clearly indicates the usefulness of this technique as a design tool; its general advantages and disadvantages are discussed by comparison with the stress freezing and slicing technique.
