The crack energy density was proposed by the author as one of the most important crack parameters, of which the physical meaning is clear throughout the life of a crack. In this paper, this crack energy density is applied to the problem of fatigue crack growth and it is tried to establish it as the parameter which is available from the first to the last of the life of fatigue crack. The results are as follows ; (1) The role of crack energy density as a crack parameter is made clear. (2) The relationship between the range of crack energy density, Δε and the load-displacement curves of specimens is obtained and it is shown that Δε is useful as a fatigue crack parameter throught the life. (3) It is shown that the growth rate of fatigue crack is determined by the increment of crack energy density per one cycle, Δε^t_<cycle> and the gradient of the distribution of crack energy density.
