2D contact smooth formulation based on the mortar method

Tur Valiente, Manuel; Giner Maravilla, Eugenio; Fuenmayor Fernández, Francisco Javier; Wriggers, P. (Elsevier, 2012)

In this paper, we apply a smoothing technique to solve contact problems using a segment-to-segment formulation based on the mortar method. In contact smoothing the C 0 finite element description of the geometry is replaced ...
A comprehensive model of the railway wheelset-track interaction in curves

Martínez Casas, José; Di Gialleonardo, Egidio; Bruni, Stefano; Baeza González, Luis Miguel (Elsevier, 2014-09-01)

Train-track interaction has been extensively studied in the last 40 years at least, leading to modelling approaches that can deal satisfactorily with many dynamic problems arising at the wheel/rail interface. However, the ...
A modified perturbed Lagrangian formulation for contact problems

Tur Valiente, Manuel; Albelda Vitoria, José; Navarro Jiménez, José Manuel; Ródenas García, Juan José (Springer Verlag (Germany), 2015-04)

The aim of this work is to propose a formulation to solve both small and large deformation contact problems using the finite element method. We consider both standard finite elements and the so-called immersed boundary ...
An enhanced energy conserving time stepping algorithm for frictionless particle contacts

Bravo Pareja, Rafael; Pérez-Aparicio, José L.; Laursen, T.A. (Wiley, 2011-03-18)

An Enhanced Energy Conserving Algorithm (EECA) formulation for time integration of frictionless contact-impact problems is presented. In it the energy, linear and angular momentum are conserved for every contact using an ...
Contact problem modelling using the Cartesian grid Finite Element Method

Navarro Jiménez, José Manuel (Universitat Politècnica de València, 2019-07-29)

[ES] La interacción de contacto entre sólidos deformables es uno de los fenómenos más complejos en el ámbito de la mecánica computacional. La resolución de este problema requiere de algoritmos robustos para el tratamiento ...
Large deformation frictional contact analysis with immersed boundary method

Navarro-Jiménez, José-Manuel; Tur Valiente, Manuel; Albelda Vitoria, José; Ródenas, Juan José (Springer-Verlag, 2018)

[EN] This paper proposes a method of solving 3D large deformation frictional contact problems with the Cartesian Grid Finite Element Method. A stabilized augmented Lagrangian contact formulation is developed using a smooth ...
Lo que hay en mí que también es vuestro. Intercambio, contacto y práctica interdisciplinar

López Montaner, Rocío (Universitat Politècnica de València, 2024-10-31)

[ES] Lo que hay en mí que también es vuestro es un proyecto de Trabajo de Fin de Grado constituido por un conjunto de obras de carácter multidisciplinar, fundamentalmente acciones, fotografías, vídeo, etc, donde el cuerpo, ...
Mejora del modelo de interacción dinámica pantógrafo-catenaria

Gómez Monterde, Javier (Universitat Politècnica de València, 2014-07-30)

[EN] The main objective of this Master’s Thesis is the development of a dynamical interaction simulation model between pantograph and catenary in high speed lines by means of the finite element method. The formulation of ...
On the effect of the contact surface definition in the Cartesian grid finite element method

Navarro-Jiménez, José-Manuel; Tur Valiente, Manuel; Fuenmayor Fernández, Francisco-Javier; Ródenas, Juan José (Springer-Verlag, 2018)

[EN] The definition of the surface plays an important role in the solution of contact problems, as the evaluation of the contact force is based on the measure of the gap between the solids. In this work three different ...
PIEL TE TOCA TEXTO. El libro de artista como respuesta a los procesos de creación.

Gómez, Marcela Verónica (Universitat Politècnica de València, 2022-07-13)

[EN] ABSTRACT SKIN TOUCHES YOU TEXT. The artist's book as a response to the creation processes, is a project whose purpose is to deal with the identity through analysis, reflection and relationship of the works carried out ...
Refined Element Discontinuous Numerical Analysis of Dry-Contact Masonry Arches

Pérez-Aparicio, José L.; Bravo, R.; Ortiz Rossini, Pablo (Elsevier, 2013-03)

The behavior of buried masonry arches is studied in this article using the Discontinuous Deformation Analysis (DDA), a numerical method that allows for the physical simulation of the intrinsic structure dis- continuities ...
Superconvergent patch recovery with constraints for three-dimensional contact problems within the Cartesian grid Finite Element Method

Navarro-Jiménez, José-Manuel; Navarro-García, Héctor; Tur Valiente, Manuel; Ródenas, Juan José (John Wiley & Sons, 2020-03-30)

[EN] The superconvergent patch recovery technique with constraints (SPR-C) consists in improving the accuracy of the recovered stresses obtained with the original SPR technique by considering known information about the ...
The Taylor expansion of the exponential map and geometric applications

Monera, M.G.; Montesinos Amilibia, Ángel; Sanabria Codesal, Esther (Springer Milan, 2014-09-01)

In this work we consider the Taylor expansion of the exponential map of a submanifold immersed in Rn up to order three, in order to introduce the concepts of lateral and frontal deviation. We compute the directions of ...
