Experimental study on the influence of temperature on the mechanical properties of granite under uni-axial compression and fatigue loading

► As the heating temperature increases, the peak stress and elastic modulus of heated granite decreases, while the peak strain increases. ► For a heating temperature below 400°C, the effect of temperature on peak stress, elastic modulus, and peak strain of granite is relatively small. ► When the heating temperature is below 400 °C, the fatigue life can be considered to depend only on the values of σm(T)/σf(T) and σa(T)/σf(T). When the temperature is over 400 °C, the fatigue life decreases as the temperature increases for given values of σm(T)/σf(T) and σa(T)/σf(T). ► There is a linear relationship between the damage parameter and fatigue life.
