Temperature-dependence of the fatigue toughening magnitude and frequency characteristics. a Fatigue fracture energy ΓFatigue of polymer-metal-MPTMS-silica interfaces for 24 °C ≤ ΔT ≤ 59 °C, at \(p_{{\mathrm{H}}_{2}{\mathrm{O}}}\) = 1.3 kPa. b The ΓFatigue trailing edge frequency νTrailing (magenta squares), leading edge frequency νLeading (green triangles), and c ΓFatigue peak height ΓFatigue-peak (blue circles), plotted as a function of ΔT. The ΓFatigue-peak and νTrailing values shown for ΔT = 24 °C represent the lower bounds (open symbols) because the νTrailing edge at this temperature extends beyond our instrument frequency range. Each data point in b and c is extracted from the corresponding curve in a. The width of the bands, drawn through the data points to guide the eye, connote the experimental uncertainties measured as standard deviation
