抄録

In parts I and II of our study, the energy-release rate of the 90°layer has been theoretically calculated and experimentally shown to be constant during cracking damage evolution. Part III establishes the damage evolution law utilizing the experimental fact that the energy-release rate of the 90°layer is constant during damage evolution. Taking account of the statistical nature of cracking position, it is possible to obtain an analytical expression of the relation between the laminate stress and the crack density, i.e., the damage evolution law. The theoretical damage evolution law shows excellent agreement with experimental results of the present study. The experimental results obtained by other researchers can also be explained by the proposed evolution law.
