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...

The paper presents the results of theoretical research scientific works on determining durability fixed rolling bearing joints with restored anaerobic sealants, develops a scheme angular mixing outer ring at deformation adhesive layer, and derives analytical dependence absolute elongation layer in operating conditions.

This paper deals with modeling of the contour evolution of heavy plates in hot rolling. During the rolling process asymmetric rolling conditions, such as temperature gradients or non-homogeneous input thickness profiles, may lead to a non-rectangular plate contour. A continuum mechanics approach is employed to systematically derive the contour evolution of the plate based on the input and outpu...

Selectin-mediated tethering and rolling initiates the multi-step process of leukocyte extravasation which is crucial for the formation of an inflammatory infiltrate. We studied the impact of platelets on this process in the skin. Using intravital microscopy, we analyzed platelet interactions with cutaneous post-capillary venules of mouse ears and observed an increase in platelet rolling if plat...

Molecular dynamics simulation of a five-site model of methane within zeolite NaCaA and ab initio calculations have been reported. Methane shows a preferential orientation during its passage through the eight-ring window. Partial freezing of certain rotational degrees of freedom is observed during the passage of methane through the eight-ring window, which acts as a bottleneck for diffusion of m...

In passenger railway optimization one of the main goals is to make efficient plans that can accommodate all passengers or, if that is not possible, that minimize the seat shortages. In the planning process, a railway operator tries to match the demand by first selecting an appropriate timetable followed by a matching rolling stock schedule. We focus on the second stage where a rolling stock sch...

The objectives in the cold rolling process include improved sheet surface quality, enhanced steel mechanical strength, and better solidification operations. Given the increasing demand for higher steel...
