Measurement of the Interfacial Stresses in Rolling Using the Elastic Deformation of the Roll

Journal of Engineering for Industry, 1987
A new method to measure the frictional stresses and normal pressure in the roll gap during cold rolling, and experimental verification of this new method, are presented. The method overcomes many of the shortcomings of pin-type sensors. The elastic deformation of the roll itself is measured with strain gages, and is used to calculate the stresses ...

Stress-Strain Analysis of Back-up Roll with Roll-Sleeve

Applied Mechanics and Materials, 2011
The back-up roll with roll-sleeve was studied and simulated using the finite element analysis software Abaqus in this paper. The stress-strain field of back-up roll with different roll-sleeve thickness and different magnitude of interference were compared because these two parameters are of importance for us to guide the application of roll with sleeve.

Rolling Element Fatigue and Macroresidual Stress

Journal of Lubrication Technology, 1970
An experimental investigation was made to determine the effect of the initial or residual stress state on rolling element fatigue life. This was done by simulating a residual stress by a mechanically applied static stress. Hoop-shaped specimens were statically stressed in both a tangential direction and a transverse direction to simulate either a ...

Thermal Stress Evolution of the Roll During Rolling and Idling in Hot Strip Rolling Process

Journal of Thermal Stresses, 2014
This study examined a critical idling time for the roll to attain a target temperature prior to rolling the next strip in the hot strip rolling process. Thermoelastic finite element simulations were performed to compute the temperature evolution and resulting thermal stress variations of the roll during rolling and idling.

Contact Stresses in Rolling Bearings

2016
The Hertzian pressure (normal stress) in the contact zone between the ball/roller and raceways causes a plastic deformation of the ball/roller contour. In the contact area, the oil-film thickness is nearly constant at the height h c and reduces to the height at h min at the outflow of the contact zone (cf. Chap. 4). The Hertzian pressure p H in the oil

Contact Stresses in the Rolling of Metals—1

Journal of Applied Mechanics, 1948
Abstract Special equipment is described which was designed and constructed to investigate the distributions of the normal pressures and the longitudinal and transverse shearing stresses along the arc of contact during the rolling of metals between plain cylindrical rolls.

Acoustoelastic Stress-Measurement in Rolled Materials

Japanese Journal of Applied Physics, 1981
A new ultrasonic method is proposed for plane-stress determination in materials with slight orthotropy. This method is, in principle, based on the stress-acoustic relations previously proposed by the author, and utilizes an ultrasonic reflection technique, in which a reference specimen without stress is used together with a specimen to be measured ...

Residual stresses in cold-rolled profiles

Construction and Building Materials, 1987
Abstract Structural steel members obtained by cold-forming have become more and more popular in steel construction. They allow for lightening the weight and thus provide appreciable savings over conventional hot-rolled sections. Cold-forming leads to changes in the main structural characteristics of the virgin material.

Research of contact stresses during rolling

2023
The research provides a methodology and results of experimental research of contact stresses in the nonstationary process of strip rolling, i.e., the rolling with an increasing rear tension before it slips in the rolls. There is used a polarization-optical modeling method.
