Book 1992een one of the major problems facing engineers for many years, and so the extension of X-ray methods to the use of neutrons represents a major advance. The technique utilizes the unique penetrating power of the neutron into most engineering materials, combined with the sensitivity of diffraction, to

Role of Neutron Diffraction in Engineering Stress Analysisress on fatigue crack propagation and interpreted in terms of fracture mechanics concepts. It is shown how neutron diffraction results can be used to validate engineering stress analysis calculations and provide information on how fabrication processes can be adjusted to achieve improved resistance to failure in components.

Comparison Between Finite Element Calculations and Neutron Diffraction Measurements of Residual Strepancies between measurement and calculation. The measurements, which were made with a conventional diffractometer as well as by time-of-flight diffraction, show up the inadequacy of the assumption of a single valued stress field.

The Effects of Crystalline Anisotropy on the Elastic Response of Materialsallographic planes. The anisotropy effects predicted be the simple Reuss and Voigt theories will be described. Recent measurements on initially stress-free samples placed under defined stresses up to and beyond their yield point are shown These can give a valuable insight into both the elastic and plastic properties of metals.

Spatial Resolution and Strain Scanningize, shape and location of the “gauge volume” are discussed. Examples are presented of the methods and equipment employed to optimise measurements made at surfaces and internally in a range of components of different shapes, sizes and residual stress distributions.
