Study on Fatigue Test and Life Prediction of Polyurethane Cement Composite (PUC) under High or Low Temperature Conditions

Figure 11

Fatigue life results and fitting curves at different temperatures: (a) T = −50°C, (b) T = −40°C, (c) T = −30°C, (d) T = −20°C, (e) T = −10°C, (f) T = 0°C, (g) T = 10°C, (h) T = 20°C, (i) T = 30°C, (j) T = 40°C, and (k) T = 50°C. Note: the data points with symbol in the figure indicate that the fatigue life is greater than 2 × 10⁶ times.
