Cyclic plastic dissipated energy and fractal dimension of fracture surfaces are selected as damage variable to evaluate the fatigue lifetime. The accumulated formula of plastic dissipated energy is established on the basis of considering cyclic deformation character of zirconium and zircaloy-4. The test results indicate that the relationship between cyclic plastic dissipated energy and fatigue lifetime fits power law. Fractal analysis of fracture surface shows that the relationship between fractal dimension and fatigue lifetime can be also expressed as power law. An empirical formula describing the relationship between dissipated energy, fractal dimension and fatigue lifetime, D ≈ 0.027 lnN f + 1.099 ≈0.120 lnWpf- 0.025, is obtained, and their physical mechanism is discussed thermodynamically.
