Paper Abstract

The aerospace industry makes large use of aluminum components, which must undergo severe fatigue tests simulating the real loads at which they will be subjected. The problem is that the high thermal diffusivity and the low frequency at which fatigue tests on real components can normally be performed often prevent the achievement of adiabatic conditions, and the attainment of quantitative results. Starting on the study of models involving different kinds of mono-dimensional stress distributions, the temperature attenuation can be evaluated and linked to the phase shift. The result is independent from the load applied and from the material. A computer program has been elaborated to correct non adiabatic TSA results on the base of the relation phase shift - attenuation.
