Abstract
A finite element analysis was described for the upsetting of a cylindrical specimen between two parallel rigid dies. The benefits of radial and longitudinal ultrasonic oscillation of the die in compressive deformation of a model soft solid were studied. The influence of oscillation direction on the interfacial friction boundary condition and thermal effects during the process was investigated. It was observed that oscillation in the radial direction results in greater reductions in forming force and friction.
