Stress-strain relationships have been traditionally derived following a phenomenological ap- proach. Here, we adopt a microstructural mechanics approach to model the development of fracture in con- crete. The concrete is assumed to have an underlying microstructure of lattice type. The micro-mechanically based stress-strain relationship is incorporated into a finite element method to evaluate its performance. Uni- axial tensile tests are simulated using different sizes of the finite element mesh. A comparison with experi- mental results has been studied.
