Abstract

The volume of the porous material in forming cannot be constant. However, the mass of the porous material remains constant; thereby making the derivations more complicated. A plastic mechanics analytical model with constant shear friction based on the slab method in this study is to explore the characteristics of the rotating compression of a porous cylinder. The effects of the frictional factor and frictional angle on the vertical stress, radial stress, average pressure, compression force, and rotating torque are systematically studied. The analytical results could be advantageous to the industries related to the forging of porous materials.
