The goal is twofold. First, to characterize their compressibility features for their classification. Second, to select a suitable material for further breakage studies that can be compared with numerical simulations of fragile particles. Eight different particulate materials were tested, both real- and model-shaped, and both inorganic and organic. The compression was performed using four different instruments to cover a wide range of loads. Based on the results obtained, according to their compressibility, the particles can be divided into several classes: elastic materials (glass fibres), breakable /fragile/ materials (rod-like graphite, hair-like pasta, rod-like pasta), hard cohesive materials (terephtalic acid), and hard non-cohesive /cohesion-less/ materials (KMnO4, PbCl2). The class of breakable materials was selected for further studies. The hair-like pasta was excluded, since its shape is ill-defined. Thus, the two candidates remained: rod-like pasta and rod-like graphite. They were examined for certain strength-related material properties in the threepoint rigidity test (consistency, stiffness, bending moment etc.).
