The photoelastic technique was applied to capture in situ plane stress in a block-on-cylinder contact. This method allows researchers to qualitatively visualize the distribution of principal stress difference during wear processes. Additionally, numerical simulation of the evolution of wear was conducted. The conjugate gradient method together with fast Fourier transform was employed to solve the...
This paper describes an experimental setup that allows the observations of the stress distribution under soft elastohydrodynamic lubrication (EHL) in line contact by means of photoelasticity. This experimental method is rarely used in the EHL field. The photoelastic fringe patterns in the circular polarization are collected under different rolling speeds and loads. Numerical calculations are carried...
