Rigid-plastic Finite Element Analysis for the Characteristics of Deformation in Upsetting Solid Cylinders
강소성 유한요소법 에 의한 중실 원통봉 업세팅 의 변형 특성 해석
Abstract
In this study the rigid-plastic finite element method is used in order to study the deformation characteristics of solid cylinder upsetting. The effects of friction and aspect ratios on the effective strain distribution, axial stresses at the die-material interface, radial displacements, strain components, grid distortion on the meridional cross-section and gradual changes of outer profile are studied analyzed and compared with the experiments for commercially pure aluminum and .alpha.-brass. The agreement between numerical (or theoretical)and experimental results is shown to be acceptable for the engineering purpose.
