Fatigue of structures and Materials in the 20th century and the state of the art
International Journal of Fatigue, 2003Co-Authors: J SchijveAbstract:The paper surveys the historical development of scientific and engineering knowledge about Fatigue of Materials and structures in the 20th century. This includes Fatigue as a material phenomenon, prediction models for Fatigue properties of structures, and load spectra. The review leads to an inventory of the present state of the art. Some final remarks follow in an epilogue.

a self aligning four point bend testing rig and sample geometry effect in four point bend Fatigue
International Journal of Fatigue, 1999Co-Authors: T Zhai, Yigeng Xu, John Martin, Angus J Wilkinson, G A D BriggsAbstract:Abstract A self-aligning four-point bend testing rig was designed and made which can minimise the possible misalignment associated with a four-point bend test and be used to study the Fatigue of Materials both at room and elevated temperatures. The stress distribution between the inner-rollers in a specimen under four-point bend, that is the nominal pure-bending section length, was analysed with respect to various load-span/specimen-thickness ratios ( t / h ) and support-span/load-span ratios ( L / t ) using a finite element method. It was found that the stress distribution could vary with both t / h and L / t . It was found that values of t / h and L / t between 1.2 and 1.5 and between 4 and 5, respectively, were the optimum testing geometry which led to a relatively uniform stress distribution consistent with the value calculated by beam theory. Fatigue tests ( R =0.1 and frequency=20 Hz) were carried out on samples with different thickness in a peak-aged 8090 Al–Li alloy using the rig. The results appear to support the finite element results. The S – N curve of the 8090 Al–Li alloy was measured using the optimum testing geometry in the four-point bend, and it was found to be consistent with that reported in the literature.
