تحلیل سه‌بعدی اکستروژن مستقیم با روش قاچی و المان محدود

Amin Samadi Ghoushchi; Caren Abrinia; Mohammad Kazem Besharati Givi

Volume 43, Issue 4 , September 2009, , Pages 527-535


  Slab method of analysis has been used for solving metal forming problems for a long time. However it has been restricted to plane strain and axisymmetric problems due to limitations in its formulations. In this paper a new formulation has been proposed so that it could be applied to three dimensional ...  Read More

اکستروژن سه بعدی به روش میدان خطوط لغزش

Caren Abrinia; Rahim Tahriri Masoule

Volume 42, Issue 1 , April 2008, , Pages 1-13


  Many metal forming problems have been solved using the slip line field method but all of them have either been two-dimensional (plane strain or plain stress) or axisymmetric problems. In this paper a procedure has been proposed by which the slip line field solution to three dimensional problems of metal ...  Read More

شبیه سازی سه بعدی فرایند اکستروژن مستقیم خارج از مرکز با روش اجزاء محدود و مقایسه با نتایج تجربی

Caren Abrinia; Jalal Pour Hosseini Baboddashti

Volume 41, Issue 4 , November 2007, , Pages 369-377


  In this paper the eccentric forward extrusion of sections has been simulated and analyzed using FEM Abaqus-explicit. The results have been compared to those obtained from upper bound theorem and experimental works. Close agreements was observed between the FEM and experimental work and as compared with ...  Read More
