Theories concerning the three-dimensional stress distribution and density distribution within the compressed powder-like material layer are generally very difficult to solve but, in the case of one-sided compression without twisting by the disc-type flat punch, approximate elucidation can be obtained by the introduction of experimental data and some hypotheses. As an example, a solution for calculating the stress distribution and density distribution is given for each of the compressed state equations for powder-like material Considering the experimental fact that, in one-sided compression without twisting by the disc-type flat punch, powder-like material inside the compressed layer do not move in the direction of radius and circumference, or their movement can be neglected, their movement can be approximated as deformation in the direction of compression, and assumption of linear approximation in γ-direction and exponential approximation in % direction, gives approximate solution by taking initial and boundary conditions into consideration. The assumptions introduced were examined for their appropriateness based on experimental results obtained in past studies.
