スポンサーリンク
概要
- 論文の詳細を見る
This paper describes the critical back pressure which prevents the central cracking of a product during hydrostatic extrusion of magnesium in correlation between the experimental and analytical results. The strain and the hydrostatic component of stress at the center axis of the billet in extrusion are obtained by applying the slip line field analysis. The analytical estimation of the critical back pressure is in good coincidence with the experimental result reported previously.
