In this study, the method of peanut shelling is selected as application of pressure on peanut bulk for the design of shelling machine and thus behavior of peanut bulk has been investigated. To this end, medium-size peanuts have been placed inside an iron cylinder of 70 mm height and 90 min diameter to form one, two and three layers, each singly at a time and have been subjected to the static pressure through a wooden piston fitted with the cylinder in a 20 ton universal testing machine under the constant loading speed. Values of loads and corresponding deformations have been recorded by the machine on a graph. The experimental data have been transformed into the linear and nonlinear models of stress-strain and pressure-density relationships.
