The report discusses very briefly the theory of fatigue, i.e., the capacity to predict accurately crack nucleation and propagation behavior with respect to cyclic stress amplitude, component geometry, cyclic frequency, material nature, temperature and environment. Although a century of testing has accumulated an enormous body of results, designers still have to resort to testing on a major scale when they attempt a new structure. A reliable theory of fatigue would bring considerable savings to such ventures.
