Abstract
In the paper an experimental and numerical analysis of fracture of cement-based composites and sandstone is given. Tensile fracture in this class of brittle disordered materials is a complicated growth process from distributed tensile cracking to crack face bridging. Experimental evidence for crack face bridging is shown, using different crack detection techniques. The fracture process is simulated using a simple lattice model. In the model the material is schematised at the meso-level as a network of brittle breaking beam elements. Heterogeneity is introduced following different concepts. A simple fracture law suffices to simulate the complex crack geometries that have been observed in the experiments.
