Stress analysis of rotating disks☆☆☆

Nuclear Engineering and Design, 1965
Abstract The equilibrium of a disk with variable thickness, symmetrical with respect to both its axis and its midplane, is analyzed, under the action of centrifugal and thermal loading. Introducing the customary assumption of plane stress, and neglecting the influence of shear stresses, the differential equilibrium equation is integrated, and stress ...

Rotating Ring-Disk Electrode Method

2014
In this chapter, the importance of rotating ring-disk electrode (RRDE) fundamentals and practical usage in an oxygen reduction reaction (ORR) study is emphasized in terms of both the electron-transfer process on electrode surface, diffusion-convection kinetics near the electrode, and the ORR mechanism, particularly the detection of intermediate such as

Maglev rotating disk laser

Chinese Optics Letters, 2015
We propose and demonstrate a laser-diode-pumped, maglev rotating Nd:YAG disk laser. The disk of the laser crystal is attached to a maglev pyrolytic graphite disk and is rotated by compressed gas. In this rotating disk laser, the detrimental thermal effects are alleviated and the laser can be operated in the single transverse electromagnetic (TEM)00 ...

Free Rotating Disk

2009
This chapter represents a validation of the present integral method for the case of a single rotating disk. It was shown that the present integral method is essentially more accurate and enables modelling a wider range of the thermal boundary conditions than the methods of other authors.

On rotating disk flow

Journal of Fluid Mechanics, 1987
The relationship of the axisymmetric flow between large but finite coaxial rotating disks to the von Kármán similarity solution is studied. By means of a combined asymptotic – numerical analysis, the flow between finite disks of arbitrarily large aspect ratio, where the aspect ratio is defined as the ratio of the disk radii to the gap width separating ...

The anisotropic rotating disks

International Journal of Mechanical Sciences, 1975
Abstract This paper analyzes the stresses generated, in closed form, in rotating disks or cylinders made of general orthotropic material. The radial and circumferential stresses in a rotating circular disk are functions of radial co-ordinates only and shear stress is equal to zero. However, the deformed shape does not remain circular.

Constant Thickness Rotating Disk

2012
For the constant thickness disk (h = cost; dh/dr = 0), the solving differential equation (1.28) is specialized in the following form: $$ \frac{{{{d}^2}u}}{{d{{r}^2}}} + \frac{1}{r} \cdot \frac{{du}}{{dr}} - \frac{u}{{{{r}^2}}} - \left( {1 + \nu } \right) \cdot \alpha \cdot \frac{{d{\rm T} }}{{dr}} + \left( {1 - {{\nu }^2}} \right) \cdot \frac ...
