13th International Conference on Fracture June 16-21, 2013, Beijing, China 5. Conclusions The strength of the material has been evaluated via simulation of discrete cohesive zone model and microscopic structures bound with cohesive zone model. By changing the morphology of the interface, sophisticated design of the strength and the properties of crack propagation of material will be possible.
