Investigation and prediction of damage propagation in painting-like samples using S–N curves

• Experimental framework for quantifying vibration-induced fatigue in painting-like materials. • Controlled long-term testing enables generation of material-specific S–N curves. • Eigenfrequency monitoring provides an objective indicator for fatigue progression. • Artificial aging affects mechanical behavior and fatigue lifetime. • Defined vibration thresholds support risk assessment for artwork transport and preservation.
