Analysis of Al-Cu Bimetallic Bars Properties After Explosive Welding and Rolling in Modified Passes
The paper presents the results of the experimental tests of Al-Cu bimetallic bars rolling process in multi-radial modified passes. The bimetallic bars consist of aluminium core, grade 1050A and copper outer layer, grade M1E.

Orbital Support of Fast and Slow Inner Bars in Double Barred Galaxies
We analyze how the orbital support of the inner bar in a double-barred galaxy (nested bars) depends on the angular velocity (i.e. pattern speed) of this bar. We study orbits in seven models of double bars using the method of invariant loops. The range of

Bulges or Bars from Secular Evolution?
We use high resolution collisionless $N$-body simulations to study the secular evolution of disk galaxies and in particular the final properties of disks that suffer a bar and perhaps a bar-buckling instability.

Theoretical and experimental analysis of the Cu-Al bimetallic bar rolling process [PDF]
In this study, the authors present the results of their theoretical and experimental analysis of the rolling process of Cu – Al bimetallic bars in elongation passes. The original bars were round aluminium bar, covered with copper layer.

Effect of shear and rotatory inertia on the bending vibration method without weighing specimens
This study examines the effect of shear and rotatory inertia on the accuracy of the vibration method with additional mass (VAM). Bending vibration tests were performed for rectangular bars with a width of 30 mm, thicknesses ranging from 5 to 60 mm, and a

Dynamic size effects across the scales: Localization in round notched bars
The strengthening and hardening of metals increase with diminishing size due to plastic strain gradient accompanied by Geometrically Necessary Dislocations (GNDs). In contrast, the inertia forces under severe dynamic loading conditions decrease.
