Three Dimensional Stress Distribution and Fracture Mechanics of Carbon/Epoxy Composite Laminates
The sub-microscopic fracture processes of carbon/epoxy laminates (CFRP) are studied numerically using the three dimensional finite element method. Several kinds of single edge notched specimens, subjected to tensile load, are analyzed. The results are compared with those of experiments and fracture toughness value of CFRP with fiber breaking, Kcf, is estimated.
