- 論文の詳細を見る
The rigid-plastic finite element method based on the plasticity equation for porous metals has been extended and applied for the analysis of plastic deformation of ordinary pore-free metals. The relative density is assumed to be very close 100%, eg. 99.5% or 99.95% in the calculation. The stress and strain states can be calculated with this method up to large deformation. Upsetting of a cylindrical billet with grooved dies and compression of square and rectangular thin plates with flat dies without lubrication are analysed. The analytical results of stress, load and deformed shape show good agreements with experimental results.
