this equation means that fatigue crack growth is proportional to the tear energy, and indicates that when tearing energy is decreased, fatigue life is increased. the mmt/mwnt sample exhibited a remarkable reduction in crack length, even after 10,000 cycles, and the fatigue crack growth of the mmt/mwnt (3.53) was decreased by over 142% compared to that of the mwnt/sbr (8.37).
