Gasket Problem in the Ultrahing-Pressure Apparatus

For the belt type high pressure apparatus, this paper has improved the flat model of O. Fukunaga by introducing the half-angle of the tapered anvil and calculated the pressure in the gasket as well as the supporting force of the gasket to the anvil. The calculated results agree with the experimental results quite satisfactorily. The matching between the pressure increments of gasket and pressure cell has been discussed for both belt type and cube type high pressure apparatus. This paper also explained how Murnaghan equation could be used to solve the problem connected with the unloading.
