| Outline of Final Research Achievements |
A general fatigue life prediction method for composite laminates has been established on the basis of the in-plane principal CFL diagrams that are described by means of a new four-segment piecewise-linear CFL diagram with the spirit of the anisomorphic CFL diagram approach. It has successful been applied to fatigue life prediction of unnotched and notched composites of different kinds.
