Temperature (T) and aging time (D) showed highly significant effects ( p < 0.0001), while humidity (H) also demonstrated a significant influence, with all three main factors falling below the 0.05 threshold.

Overall, these results show a clear trend: hygrothermal aging drives fracture surfaces from brittle features toward plasticization, void formation, and erosion. **Higher temperature increases erosion features.**.
