[ 1 ] - Bending Analysis of Carbon Nanotubes with Small Initial Curvature Embedded on an Elastic Medium Based on Nonlocal Elasticity and Galerkin Method
Carbon nanotubes have an important role in reinforcing nanocomposits. Many experimental observations have shown that in the most nanostructures such as nanocomposites, carbon nanotubes (CNTs) are often characterized by a certain degree of waviness along their axial direction. In the present paper, the effects of initial curvature, influence of surrounding medium that is modeled as Winkler elast...

[ 3 ] - Analyzing Effect of Friction on Spread and Budge in Flat Rolling by FEM Method
In this research a final element model for simulating three dimensional deformation in rolling of flat product is modeling in ABAQUS and further developed to study the frictional effects on spread and bulge. To predict the magnitude of bulging , the rolling process is approximated by successive forging steps. The elongation or the average spread at each step from the previous calculations are u...
[ 4 ] - A Roll Wear Prediction Model in Hot Plate Rolling
In this paper, the wear of work roll in hot plate rolling is introduced and the parameters affecting wear mechanisms in hot strip mill are investigated. In addition, different wear mechanisms in hot rolling and the differences between these mechanisms in different stands are explained. Using the finite element method and the rolling equations, a work roll wear model is proposed. Wear is modeled...
[ 5 ] - شبیه سازی ارتعاشات ناپایدار ورق در فرایند نورد سرد به کمک روش اجزاء محدود
چتر، یک مورد خاص از ارتعاشات خود تحریک میباشد که در نتیجه عکسالعمل بین سازه دینامیکی قفسه نورد و دینامیک فرایند نورد بوجود میآید. مدلی که در این مقاله مطرح شده است شامل دو زیر مدل یکی برای سازه قفسه و دیگری برای فرایند نورد (تغییرشکل ورق) میباشد. در سازه قفسه از جرمهای متمرکز برای تحلیل غلتکها و المانهای فنر و دمپر به منظور شبیه سازی تماس غلتکها با یکدیگر و اتصال آنها به ساختمان دستگاه است...
