Damage, be it breakage, deformation or wear is initiated by overstraining or overstressina. Full modelling of both these causes is not possible today and one resorts to “simulation” to produce the data needed by design engineers to predict function loss. The question then is: how reliable is the data furnished by simulation? The answer is brought by the analysis of data produced in fretting tests which show that even very small variations in running conditions, in this case in amplitude, can change the nature of the damage. Simulation tests have to be undertaken with the utmost care.
