	Presented paper contains results of fracture analysis of brittle composite materials with a random distribution of grains. The composite structure has been modelled as an isotropic matrix that surrounds circular grains with random diameters and space position. Analyses were preformed for the rectangular finite element models. These models were generated using the author's computer program RandomGrain. Fracture analyses were accomplished with the author's computer program CrackPath3 executing the "fine mesh window" technique and new strategy for determining the direction of crack propagation. Calculations were preformed in 2D space assuming the plane stress state. Current efforts focus on brittle geo-materials such as rocks or concrete.
