Normal Vibrations and Friction Under Harmonic Loads: Part I—Hertzian Contacts
D. P. Hess,Andres Soom +1 more
TLDR
In this paper, nonlinear vibrations at a Hertzian contact are studied by the perturbation technique known as the method of multiple scales, and the average normal contact deflection during oscillations is smaller than the static deflection under the same average load.Abstract:
Nonlinear vibrations at a Hertzian contact are studied by the perturbation technique known as the method of multiple scales. As a result of the nonlinear Hertzian stiffness, the average normal contact deflection during oscillations is smaller than the static deflection under the same average loadread more

Self-dispersed crumpled graphene balls in oil for friction and wear reduction.
Xuan Dou,Andrew R. Koltonow,Xingliang He,Hee Dong Jang,Qian Wang,Yip-Wah Chung,Jiaxing Huang +6 more
TL;DR: For the first time to the authors' knowledge, such type of ultrafine particles made of crumpled, paper-ball–like graphene are reported, which indeed can self-disperse in lubricant oil, and exhibit stable and superior tribological performances.

The effect of amplitude of vibration on the coefficient of friction for different materials
TL;DR: In this paper, the authors examined how friction coefficients are affected by amplitude of normal vibration at different frequencies and found that the rate of reduction of friction coefficient has a particular relationship on the amplitude and frequency of vibration.
