Webb13 okt. 2024 · Due to the brittle failure of the wear part (RM.6), the wedge pairs (RM.4) begin to slide outwards and relieve the pressure on the moveable brake shoe (RM.3). This, in combination with the elastic rebound of the involved components, leads to a sudden release of the energy in the striker bar, which causes the pulse to form in the bar system. WebbThe failures of brittle rocks or rock-like materials under compression have been proved to be a process of crack initiation, propagation and coalescence [1,2,3,4,5,6,7].It is widely accepted that such characteristics are mainly resulted from the material heterogeneity due to different types of strong or weak minerals and microdefects in meso-level. desiree nick sohn vaterWebbbrittle material is taken up by the newly -created surfaces as surface potential energy, and is thus not available to do further 10 work.
