A lattice type model is employed to simulate the shear deformation and failure of uniform and non-uniform materials. Uniform materials are modeled as assembleges of a number of unit cells, which undergo bifurcation buckling to express the local softening behavior of materials. Nonuniform materials are represented with the use of the image-based geometry modeling with the consideration of micro-macro scale model to simulate the formation of a cross shear band.
