An enhanced version of the rotation-free three node triangular BST shell element for sheet stamping analysis is presented. The original BST element is based on an assumed constant curvature field expressed in terms of the ...

Red Aulas CIMNE: espacios de colaboración en temas docentes y de I+D en distintas universidades, empresas y centros de investigación de diversos países

Oñate Ibáñez de Navarra, Eugenio; Guzmán, Francisco; Bugeda Castelltort, Gabriel; Corestein Poupeau, Georgina; Zárate Araiza, José Francisco (Escola Universitària d'Enginyeria Tècnica Industrial de Barcelona (EUETIB), 2004)
Conference report
Open Access

La mayoría de los avances de I+D que hoy en día se producen quedan limitados en función de necesidades locales. La causa principal es la falta de medios para proyectar la I+D hacia entornos donde pueda ser exitosamente ...

Global search methods for nonlinear optimisation: a new probabilistic-stochastic approach

Bugeda Castelltort, Gabriel; Balsa-Canto, E; Thamotheram, C; Oñate Ibáñez de Navarra, Eugenio; Zárate Araiza, José Francisco (International Centre for Numerical Methods in Engineering (CIMNE), 2003)
Conference report
Open Access

In this work the problem of overcoming local minima in the solution of nonlinear optimisation problems is addressed. As a first step, the existing nonlinear local and global optimisation methods are reviewed so as to ...

Numerical homogenization and experimental validation of a composite plate using modal analysis

Pérez Martínez, Marco Antonio; Gil Espert, Lluís; Hammami, Farah; Neifar, Mondher; Chafra, Moez (2010)
Conference report
Restricted access - confidentiality agreement

A Finite Element (FE) simulation and an experimental (EXP) test are performed for the validation of the homogenized global elastic properties of a composite material plate. Composite material homogenization is based on ...

A micromechanical approach to modeling the effect of impact induced damage on the vibration response of CFRP laminates

Pérez Martínez, Marco Antonio; Gil Espert, Lluís; Oller Martínez, Sergio Horacio; Felippa, Carlos (2015)
Conference report
Restricted access - publisher's policy

This work deals with modeling the effect of low-velocity impact damage upon the vibration response of CFRP laminates through a micro-mechanical description of the induced internal damage. The serial-parallel (SP) continuum ...

Analysis of different types of cementitious-based composites used as shear strengthening system for reinforced concrete beams

Escrig Pérez, Christian; Bernat Masó, Ernest; Gil Espert, Lluís (Universidad de Cantabria, 2016)
Conference report
Open Access

The global tendency to apply sustainable criteria in most of the productive fields and the limited durability and the pathologies that reinforced concrete elements suffer are aspects that explain the increasing necessity ...

Modelling unreinforced, TRM-strengthened and FRP-strengthened brick masonry walls subjected to eccentric compressive load

Bernat Masó, Ernest; Gil Espert, Lluís; Roca Fabregat, Pedro (2015)
Conference report
Open Access

The mixed bending/buckling collapse mode of brick masonry walls might be prevented by installing strengthening systems which provide tensile strength. Among others, the Textile Reinforced Mortar (TRM) and Fibre Reinforced ...
