Abstract

Two different temperatures (room temperature and 200oC) were used in the
experiments using 1100 Aluminum alloy in order to analyze the effect of
temperature. Stress amplitude versus fatigue life (S-N curves) for two different temperatures was established experimentally. The transition lives (point) of those two curves were observed and no significant effect of temperature on this point was observed. Fatigue strength at a given number of cycles decreases with increasing temperature.
