A new stochastic micro-mechanical damage model for quasi-brittle materials subjected to monotonic and cyclic uniaxial loading is proposed in this paper. The model uses a series of microelements endowed with simple material properties, in which plastic elements are adopted to consider and record plastic deformation, to represent the overall response of the material. The elastoplastic coupling and plastic-damage coupling, as well as the heterogeneity of the material are considered in the model. Furthermore, the model can exhibit the non-linear performance and stochastic properties of the material, and the model predictions match the experimental data well.
