Effect of mean stress in high-temperature fatigue - Energy-based approach is considered for crack growth and the result is used to explain the experimental investigations carried out to study the effect of mean stress on the fatigue behavior of alpha brass at elevated temperature

Investigations have been carried out to study the effect of mean stress and temperature on the fatigue behavior of alpha brass. Introduction of mean stress reduces the fatigue life of the material, the reduction being very much pronounced in the temperature region of 0.5 Tm. Theoretical analysis based on hysteresis energy yields relations which describe well the experimental findings. © 1978 Society for Experimental Mechanics, Inc.
