Development and Applications of ALCO Method for Acquiring Elastic Constants of Friction Materials

Recently the ALCO (Anisotropic Lining elastic Constants Optimization) method for acquiring NAO material elastic constants is introduced by the authors [1]. In this paper, further development and application of ALCO method is discussed. First, two newly incorporated optimization methods are introduced, along with examples of using different optimization methods. The effect of different starting points is then discussed. Finally, a case study is provided to examine whether the elastic constants acquired from one pad assembly are still applicable to other pad and pressure plate shapes (same friction material).
