Abstract
The experimental investigations are carried out in regard to the mechanisms of elastic contacts which were introduced in 1st and 2nd report.The main results obtained are as follows:(1) The distribution of asperity heights appearing on the surface profile curve and the real distribution of them conform more satisfactorily to Gamma or Rayleigh distribution than the normal distribution.(2) The real contact area and the number of contact spots between rough and flat surfaces agree qalitatively with the calculated values. The approaches between the rough surfaces also agree qualitatively with the calculated values.(3) The shearing strength of Pyrex glass at the contact areas is about 100 to 140 kg/mm2.
