摘要: This work is focused on the mechanical characterization by multiscale indentation (nano and macro) of a brake pad material, with multiple phases complex microstructure for applications in railway industry. Grid nanoindentation tests allowed to identify properties components formulation. The significant difference between constituent’s gives quickly composite response. In parallel, multicyclic macroindentation were performed obtain change according test locations configurations staking phases, due high heterogeneity material. results demonstrated that give consistent response, which approximates at different scales. Considering such very heterogeneous material (broad distribution particle sizes), used methodology appropriate other materials. A necessary deal problematic vibrations induced friction, particularly squeal prediction.
