A DAMAGE MECHANICS TOOL FOR LAMINATE DELAMINATION

A simplified method based upon damage mechanics for the delamination a nalysis of carbon-resin composites is presented. In the neighbourhood of a laminate structure quasi-straight edge, damage is taken concentra ted on the interface between layers. The finite element code EDA, acti ng as a post-processor of an elastic laminate shell computation, allow s the onset and propagation forecast of delamination. First numerical simulations of delamination are given and compared with experimental r esults from literature.
