A review of lattice type model in fracture mechanics: theory, applications, and perspectives

The lattice model is a discrete model that is typically used to simulate the fracture process of brittle materials. This review summarizes the main achievements during the development history of the state-of-the-art lattice model during the past 80 years from the theory and application viewpoints. It is found that the classical lattice spring model (LSM) can only simulate a fixed Poisson’s ratio. This problem has been partially or fully solved...
