Modified generalized beam lattice model associated with fracture of reinforced fiber/particle composites

Lattice-type model can simulate in a straightforward manner heterogeneous brittle media. Mohr–Coulomb failure criterion has recently been involved into the generalized beam (GB) lattice model, and as a result, numerical experiments on concrete under various loading conditions can be conducted. The GB lattice model is further used to investigate the reinforced fiber/particle composites instead of only particle composites as the model did before. Numerical examples are given to show the effectiveness of the modeling procedure, and influences of inclusions (particle, fiber and rebar) on the fracture processes are also discussed.
