Abstract
It is well established that the fatigue performance of materials and structures may be very sensitive to the specifics of the loading encountered. Beside constant amplitude testing, therefore, tests with realistic load sequences are often required in order to assess any susceptibility to the specifics of variable amplitude loading and to demonstrate the in‐service integrity for given materials and structures. For these purposes standardised load‐time histories (SLH’s) have been developed for 30 years since it has been recognised that the use of SLH’s a series of advantages – both for studies of a more generic nature and practical applications. Starting with Gassner’s block programme test, some features of standardised load‐time histories available at present and their relevance for fatigue behaviour of materials and structures are reviewed.Keywords
