ABSTRACT = {An effective fracture model is established for the brittle materials with periodic distribution of micro-cracks 
using the second-order multiscale asymptotic methods. The main features of the model are: (i) the secondorder strain gradient included in the fracture criterions and (ii) the strain energy and the Griffith criterions 
for micro-crack extensions established by the multiscale asymptotic expansions. Finally, the accuracy of the 
presented model is verified by the experiment data and some typical fracture problems. These results 
illustrate that the second-order fracture model is effective for analyzing the brittle materials with periodic 
distribution of micro-cracks.},
