The plate has been subjected to cyclic load variation with a maximum load of 22.5 kN and a minimum load of 3.1 kN, with a load ratio of 0.138. The measured crack length as a function of the number of cycles is presented in Fig.2. These data are used for assessing the validity of computational prediction of FCG behaviour in plate specimen.
