A numerical and analytical study of the stress field generated by the contact between a rail and a wheel
(Springer, 2020-06-19)
This article presents a study of the contact stresses between a rail and a wheel, in order to understand the mechanism related to this application. When two bodies, regardless of their forms, touch each other due to an ...
Estimating vocal fold contact pressure from raw laryngeal high-speed videoendoscopy using a Hertz contact model
(MDPI AG, 2019)
The development of trauma-induced lesions of the vocal folds (VFs) has been linked to a high collision pressure on the VF surface. However, there are no direct methods for the clinical assessment of VF collision, thus ...
Dynamic analysis of a lubricated planar slider-crank mechanism considering friction and Hertz contact effects
(Pergamon-elsevier Science LtdOxfordInglaterra, 2014)
A study of the stress field generated by the contact between a sphere and a flat plate for a simplified model of deep-groove ball bearingUn estudio del campo de tensión generado por el contacto entre una esfera y una placa plana para un modelo simplificado de rodamientos rígidos de bolas
(2020-01-01)
Bearings are mechanical elements capable of transferring motion between two or more parts in a machine. When an external load is applied, the rolling elements and their rings tend to initiate a cyclical movement between ...
Estimating Vocal Fold Contact Pressure from Raw Laryngeal High-Speed Videoendoscopy Using a Hertz Contact Model
(2019)
Featured Application A method to directly estimate the contact pressure of the vocal folds using uncalibrated laryngeal kinematic data is presented. The approach is promising in enhancing the objective assessment of vocal ...
Time-dependent Mechanical Response at the Nanoscale
(Elsevier B.V., 2020-01-01)
Modern nanofabrication processes on metals, polymers, and ceramics often require deforming these materials at strain rates ranging ~101 – 107 s–1. Therefore, there is a need to develop an appropriate methodology capable ...
Análisis de esfuerzos durante el contacto mecánico de materiales elásticosStress analysis during the mechanical contact of elastic materials
(Asociación Física Argentina, 2016-12)
En este trabajo se calculan los esfuerzos resultantes en la región de contacto de dos materiales elásticos, a través del método de elementos finitos. Estos resultados se comparan con ecuaciones analíticas del modelo de ...
Avaliação das condições de contorno da teoria de Hertz, comparando os resultados analíticos e numéricos a partir de simulações em software de elementos finitos
(Universidade Estadual Paulista (Unesp), 2013-12-06)
The objective of this study was to present the comparison between analytical and numerical results trying to identify the differences and behaviors of the variation of the principal stresses and the maximum contact pressure ...
