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 ...
Análisis del comportamiento dinámico entre vehículos de propulsion térmica y su versión eléctrica mediante el programa Adams/Car

Viola, Marco (Universitat Politècnica de València, 2023-09-25)

[ES] Los efectos del cambio climático han dado lugar a la creación de nuevas normativas de emisiones por parte de muchas administraciones para reducir las emisiones de gases de efecto invernadero e impulsar la descarbonización ...
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 ...
Direct medical image-based Finite Element modelling for patient-specific simulation of future implants

Giovannelli, Luca; Ródenas, J.J.; Navarro-Jiménez, J.M.; Tur Valiente, Manuel (Elsevier, 2017)

[EN] In patient specific biomedical simulation, the numerical model is usually created after cumbersome, time consuming procedures which often require highly specialized human work and a great amount of man-hours to be ...
Diseño y Optimización de la estructura de una grúa orre mediante el método de elementos finitos

Sanchís Gómez, Carlos (Universitat Politècnica de València, 2018-09-06)

El diseño basado en el cálculo estructural se realiza mediante un método de prueba y error. Es decir, se propone un modelo, se realiza un cálculo estructural y el propio ingeniero modifica el modelo según los resultados ...
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 ...

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 ...
On the use of stabilization techniques in the Cartesian grid finite element method framework for iterative solvers

Navarro-Jiménez, José-Manuel; Nadal, Enrique; Tur Valiente, Manuel; Martínez Casas, José; Ródenas, Juan José (John Wiley & Sons, 2020-07-15)

[EN] Fictitious domain methods, like the Cartesian grid finite element method (cgFEM), are based on the use of unfitted meshes that must be intersected. This may yield to ill-conditioned systems of equations since the ...
