  • Analysis and comparison of European data on fatigue under variable amplitude loading gathered during the 1976-1986 European Community "Steel in marine structures" programme


Current practice in the evaluation of fatigue damage under variable loading is characterized by its diversity and constant evolution. The main methods cited in historical order are: - the Maximum Stress method - the Linear Damage Rule or Palmgren-Miner Rule - the Root Mean Square (RMS) value - the Equivalent Stress method. The focussing and presentation within the same framework of all the results obtained in the "Steel in Marine Structures" Community Program, using the current damage analysis procedures mentioned above will allow comparisons: - of results from different sources - of more or less equivalent structures - of methods adopted in relation to each other and in relation to the corresponding S-N curves. In spite of major differences in the spectra used and the geometrical form of speciments adopted, it is possible to compare a certain number of results and to draw general conclusions.
