Fig. 5: Stress–Life fatigue behavior of copy paper.
The high-cycle fatigue life (Nf) was measured as a function of the applied alternating stress range (Δσ). The fatigue lives ranged from <100 to ~106 cycles to failure for stress ranges that were bounded by the notched specimen ultimate and yield strengths, respectively (dashed lines). The error bars were smaller than the symbols used to denote the fatigue lives.
