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 ...
Evaluation of subsurface contact stresses in railroad wheels using an elastic half-space model
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2004)
Estudo analítico e numérico das tensões de Hertz em contato entre uma esfera/plano e um cilindro/plano
(Universidade Estadual Paulista (Unesp), 2019-12-02)
Neste trabalho é apresentado um estudo analítico e numérico a respeito das tensões superficiais entre dois elementos. Quando uma força externa é aplicada a dois corpos em contato, verifica-se a existência de uma pequena ...
Numerical analysis of the influence of film thickness and properties on the stress state of thin film-coated piston rings under contact loads
In this work, a series of finite element analyses was conducted to analyze the stresses in thin film-coated piston rings under contact loads. The actual normal and tangential pressure observed during a complete four-stroke ...
Influence of occlusal contact area on cusp defection and stress distribution
(2014)
The purpose of this study was to evaluate the effect of occlusal contact area for loading on the cuspal defection and stress distribution in a first premolar restored with a high elastic modulus restorative material. The ...
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 ...
Association between Contact with Nature and Anxiety, Stress and Depression Symptoms: A Primary Survey in Brazil
(Mdpi, 2022-09-01)
Mental health benefits have been linked to human interaction with nature. However, most studies have been carried out in developed countries, limiting the generalizability of empirical findings to other parts of the world. ...
Contact notch stress assessment within frictional contact joints
(Universidad Nacional de Colombia Sede Medellín, 2012)
Stress concentrations at the ends of a flat contact including frictional sliding are analyzed in this article by using the finite element (FE) method. The numerical studies are conducted with a shaft coupled to the hub by ...
Effect of Crack Patterns on the Stress Distribution of Hard Chromium Coatings under Sliding Contact: Stochastic Modeling Approach
(American Society of Mechanical Engineers, 2017-06)
In this work, the influence of different crack arrangements in the stress distribution of hard chromium (HC) coatings was determined. Three parameters for position and length of the cracks for two different types of coatings ...
Contact Stiffness Estimation In Ansys Using Simplified Models And Artificial Neural Networks
