Dry elasto-plastic contact of nominally flat surfaces
TL;DR: In this article, a method to solve dry contact problems for this purpose in the case of plane surfaces using a simple elastic-plastic model at the asperity contacts and a differential formulation for the elastic deflection is presented.

2D thermo-mechanical contact simulations in a functionally graded material : a multigrid-based approach
TL;DR: In this article, a second order finite difference (FD) formulation of the continuous thermal and elasticity equations is proposed to account for materials with continuously changing properties and to obtain an improved prediction of the resistance of such graded materials.

Modelling tribochemistry in the mixed lubrication regime
TL;DR: In this article, a semi-deterministic tribochemical model of growth is integrated in a deterministic mixed lubrication model, which considers the variable hardness of the tribofilm and enables the study of lubrication and tribochemistry.

The effect of contact severity on micropitting: Simulation and experiments
TL;DR: A numerical contact fatigue model combining the effects of rolling contact fatigue and wear has been developed based on mixed elastohydrodynamic lubrication (EHL) theory, continuum damage mechanics (CDM) and the Archard's wear law.

FT-CNN: Algorithm-Based Fault Tolerance for Convolutional Neural Networks
Kai Zhao,Sheng Di,Sihuan Li,Xin Liang,Yujia Zhai,Jieyang Chen,Kaiming Ouyang,Franck Cappello,Zizhong Chen +8 more
TL;DR: Wang et al. as discussed by the authors proposed several systematic ABFT schemes based on checksum techniques and analyzed their fault protection ability and runtime thoroughly. And they designed a novel workflow integrating all the proposed schemes to obtain a high detection/correction ability with limited total runtime overhead.
