فرایند کشش عمیق استوانه‌های با نسبت کشش خیلی بالا

Ghader Faraji; Mohammad Kazem Besharati Givi; Saeed Yarmohammadi; Mahmoud Mousavi Mashhadi

Volume 43, Issue 4 , September 2009, , Pages 519-525


  Deep drawing of cylindrical shapes with high limiting drawing ratio (LDR) values is relatively difficult. Annealing is a further operation, which in turn adds costs and consumes significantly time to the forming process. In the present work, cylindrical cups from brass sheet were made with only limited ...  Read More

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

تحلیل و بهینه‌سازی سازه‌های ساندویچی با هسته سینوسی

Mohammad Kazem Besharati Givi; Mehdi Ghasemi; Seyyed Mahmoud Mousavi Mashhadi

Volume 43, Issue 1 , April 2009, , Pages 11-20


  In this paper a special sandwich panel with a sinusoidal core under distributed load on upper and lower plates has been studied. By drawing free body diagrams, and using energy method and Castagiliano theory the forces and moments involved in the core has been determined. Then, the stresses, normal and ...  Read More

تعیین هم زمان تنش سیلان و فاکتور اصطکاک آلومینیوم 7075 به کمک روش تحلیل معکوس

Mohammad Kazem Besharati Givi; Amir Sarvari

Volume 42, Issue 5 , September 2008, , Pages 617-623


  In all engineering applications where solid surfaces slide on each other, friction plays an important role. It becomes even more important, particularly in metal forming processes where the two sliding materials are metallic. Among forming processes, forging is an important process, because of improving ...  Read More

بررسی روشهای تولید نانو تیوب های کربنی و انتخاب بهترین روش ساخت مناسب با استفاده از روش تصمیم گیری چند معیاره

Mohammad Kazem Besharati Givi; Akbar Afaghi Khatibi; Mansour Akbari

Volume 42, Issue 1 , April 2008, , Pages 49-63


  Evidence from the early and late industrializes shows that technology, as the commercial application of scientific knowledge, has been a major driver of industrial and economic development. International technology transfer is now being recognized as having played an important role in the development ...  Read More
