Nickel-phosphorous alloy foil with conical projections is used for high contact pressure measurement. The foil arranged projections high density and heated at 400℃ is possible to measure pressure about 1.5GPa. It is clarified that the real contact pressure occurred at real contact area of projections is responsible to the plastic deformation of projections. The relationship among contact pressure, plastic deformation of projections, and projection density is formulated experimentally. The contact pressure distribution between flat end of a circular cylinder and an elastic plane is measured by this method. The pressure gradually increases with approaching cylinder edge. Moreover, the pressure of center portion becomes small and the edge pressure becomes large as the modulus of rigidity of cylinder becomes high. This tendency is analogous to the numerical calculation result.
