Accumulation of Fatigue Damage Using Memory of the Material

This work proposes a new model for cumulation of fatigue failures based on material memory, developed on the grounds of memorising senseless material. Cumulation of fatigue failures (D) is based on employing time history of the trajectory and cumulation of fatigue failures with the help of a coefficient dependent on material memory. Moreover, the work presents comparison of experimental and numerical studies for P91 and P92 steels using the model developed by authors. Theoretical assumptions have been confirmed by obtained results of numerical computations.
