Calculate pressure at the mid-plane of an annular cylinder of iron powder pressed using double-action press. The punch pressure (i. e., applied pressure) is 100 MPa when the height of the pressed sample is 10 cm. The coefficient of friction is 0.1, radial-to-axial pressure ratio is 0.4, and the wall thickness of the annular compact is 2 cm.
