بررسی فرایند نورد متقارن ورق های سه لایه با استفاده از تابع جریان و تئوری حد بالا

In this paper, a mathematical model for symmetrical multi-layer sheet rolling, in which the layers are unbounded before rolling, by using the upper bound method and stream function theorem is proposed. Using this model, we can investigate the plastic deformation behavior of sheets at the roll gap du... View More
