A computational framework for modelling, simulating, and analyzing random microstructured materials is presented. Statistical analysis of experimental material measurements motivates probabilistic models for microstructures. Random tessellations and random fields are the primary tools implemented. Sample generation techniques are developed to enable the efficient simulation of material microstructures. Lastly, an example application is presented in which intergranular fracture is simulated for random polycrystals.
