In this study, the impact of agglomerates composed of autoadhesive, elastic-plastic primary particles are simulated using the discrete element method. Results obtained are compared to the impact breakage of an agglomerate of autoadhesive elastic particles. It is found that, for the same impact velocity, the elastic agglomerate fractures but the elastic-plastic agglomerate disintegrates adjacent to the impact site. For the elastic-plastic agglomerate, the impact damage increases with increase in material yield stress. It is also found that the particle size distribution of the debris is more accurately defined by a logarithmic function rather than the power law function commonly obtained for impacts of agglomerates composed of elastic particles.
