一个有效的有限元分析描述了在两个平行的刚性模具之间镦粗圆柱形试样，其中工件暴露在运动和径向或纵向超声振荡加载条件下。数值结果显示了几个参数的变化对橡皮泥模具试样界面的影响，以及应力叠加、温度和摩擦减少如何在径向和纵向模具振动方向上减少变形力。
A validated finite element analysis is described for the upsetting of a cylindrical specimen between two parallel rigid dies, where the workpiece is exposed to kinematic and radial or longitudinal ultrasonic oscillatory loading conditions. Numerical results are presented to show the effects of variation in several parameters on the die-specimen interface for Plasticine, and how stress superposition, temperature and friction reduction contribute to the reduced deformation forces, for both radial and longitudinal die oscillation directions.
