Atomistics of friction and superlubricity
When we think about friction, we usually think about the drag produced when two objects rub against each other. In industrial technology, friction is at times the force used to stop something, and at times, a problem to be prevented.
Objects come in conrtact, and friction results. Scientists have long been intrigued by this phenomenon of friction, and have recently made some new discoveries. Scientists have examined the friction phenomenon on the atomic scale, and have found cases in which zero-friction can be produced.

1．Inverse problem analysis of elastic anisotropy of materials by linking resonance frequency measurement and Rayleigh-Ritz finite element calculation
In this study, we established a precise measurement method (multimode resonance method) of the resonance frequency under free vibration using a micro test piece, and combined the finite element method and the Rayleigh-Ritz method for natural vibration analysis (FEM inverse analysis method). ) Is completed, and the purpose is to determine the elastic coefficient matrix of the anisotropy magnesium alloy with high accuracy.
