In continuation to the experimental work of Part 1, a fracture mechanics model was developed. With this model, it was intended that the adhesive failure at the particle-latex interfaces, the cohesive failures within the bodies of latex and the strength of the pigment-latex composite could be predicted. Both monodisperse and polydisperse geometries were modelled as continuum micro-structures and latex bridges were geometrically simplified to ensure easier calculations. The parameters input into the model were based on the experimental tests and by doing so, a closer and more accurate association was made between the experimental and theoretical phases of research.
