Dissipation measurements during ultrasonic fatigue tests

Résumé

The aim of this paper is to analyse the dissipation observed during dynamic fatigue loading at low stress range and high number of cycles. Infrared thermographic techniques were developed to estimate the mean dissipation per cycle. Results derived from tests performed at high loading frequency on pure copper specimens showed a drift of dissipative regimes incompatible with concepts of fatigue limit and/or asymptotic cyclic stability.
