A Coupled Eulerian Lagrangian Model to Predict Fundamental Process Variables and Wear Rate on Ferrite-pearlite Steels
(Elsevier B.V., 2017)
A coupled Eulerian-Lagrangian Finite Element model of the orthogonal cutting process was developed to predict the influence that ferritepearlite steel variants have on fundamental process variables and tool wear. As a case ...
Influence of Microstructure on Chip Formation when Broaching Ferritic-Pearlitic Steels
(Elsevier B.V., 2017)
Broaching is a specific process characterized by relatively low cutting speeds and uncut chip thicknesses. The latter is in the range of 0.1 to 0.25 mm in the roughing section of the tool but can decrease down to 0.0015 ...
The CEL Method as an Alternative to the Current Modelling Approaches for Ti6Al4V Orthogonal Cutting Simulation
(Elsevier B.V., 2017)
The finite element approach is often adopted to study the machining process. The Lagrangian and Eulerian formulations or even Arbitrary Eulerian-Lagrangian (ALE), one of their combinations, are the most employed in the ...
Numerical simulation of the roll levelling of third generation fortiform 1050 steel using a nonlinear combined hardening material model
(IOP Publishing Ltd, 2017)
Elasto–plastic behavior of the third generation Fortiform 1050 steel has been analysed using cyclic tension–compression tests. At the same time, the pseudo elastic modulus evolution with plastic strain was analysed using ...
U-drawing of Fortiform 1050 third generation steels. Numerical and experimental results
(IOP Publishing Ltd, 2017)
Elasto–plastic behavior of the third generation Fortiform 1050 steel has been analysed using cyclic tension–compression tests. At the same time, the pseudo elastic modulus evolution with plastic strain was analysed using ...
Simulation-based testing of highly configurable cyber-physical systems: automation, optimization and debugging
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2017)
Sistema Ziber-Fisikoek sistema ziber digitalak sistema fisikoekin uztartzen dituzte. Sistema hauen aldakortasuna handitzen ari da erabiltzaileen hainbat behar betetzeko. Ondorioz, sistema ziber-fisikoa aldakorrak edota ...
Análisis del Springback y de la conformabilidad del Inconel 718 en procesos de embutición a temperatura ambiente
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2017)
Tal y como ocurre en otros sectores, el propósito de la reducción de emisiones de CO2 en el sector aeronáutico viene dado por el acuerdo internacional del protocolo de Kyoto (Naciones unidas 1998). El objetivo principal ...
Análisis de los esfuerzos generados en los frenos de embutición y desarrollo de un modelo semi-analítico de predicción de los esfuerzos de enclavamiento
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2017)
Embutizio frenoak automobil komponenteen embutizio prozesua kontrolatzeko eta prozesu egokia lortzeko elementu funtsezkoenetariko bat da. Fabrikazio prozesu simulazioaren konputazio denboraren murrizketa beharra dela eta, ...
The crew scheduling problem of an interurban public transport bus company
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2017)
Una planificación de los conductores adecuada impacta en el coste operacional de las empresas de transporte público. La dificultad de esta tarea se debe principalmente a dos aspectos (Esclapés 2001, Bonrostro, Yusta 2003, ...
Filtered multi-carrier modulations for industrial wireless communications based on cognitive radio
