Figure 4

The calculated details of the contact area by plastic deformation under different punch pressures at 1,700 °C and the corresponding relative densities.

(a) The relationship between the contact force and the contact area under different punch pressures from 30 to 100 MPa. (b) The relationship between relative density and the contact area for a packed grain structure.
