Abstract : A monograph is presented which details the analysis and experiment on the mechanics of sub-laminate crack propagation in polymer-based composite laminates. The analytical approach is based on the energy release rate concept of the classical fracture mechanics, in conjunction with a numerical crack propagation simulation technique using finite elements. Main emphasis is placed on statically induced cracks, although fatigue induced cracks are also discussed. (Author)
