  • Analysis of the decrease of the apparent young's modulus of advanced high strength steels and its effect in bending simulations 

    Cobo Molina, Raúl; Pla, M.; Hernández Rossi, Ricardo; Benito Páramo, José Antonio (2009)
    Conference lecture
    Open Access
    In this paper the evolution of the Young’s Modulus (E) during unloading with plastic deformation has been studied for different Dual-Phase AHSS from DP780 to DP1400. During unloading, all the DP steels studied showed the ...

    Hernández Rossi, Ricardo; Cruz, Marlon; Casellas Padró, Daniel; Riera Colom, María Dolores; Prado Pozuelo, José Manuel (2007)
    Article
    Open Access
    En el sector automovilístico se ha incrementado el uso de aceros de alta y muy alta resistencia para conformar piezas de carrocería. La utilización de estos nuevos aceros lleva asociada una problemática específica en la ...
  • FLSD as a good choice in sheet forming of AHSS 

    Hernández Rossi, Ricardo; Llobet Lorenzo, Alberto; Gómez, X.; Riera Colom, María Dolores (Dassault Systèmes, 2011)
    Conference report
    Open Access
    The automotive industry has increased significantly the use of advanced high strength steels (AHSS) in many structural components, with the aim to reduce weight and also to increase safety. The high resistance of these ...
  • Fluid-structure interaction problems with strong added-mass effect 

    Idelsohn Barg, Sergio Rodolfo; Pin, Facundo del; Hernández Rossi, Ricardo; Oñate Ibáñez de Navarra, Eugenio (2009-07)
    Article
    Restricted access - publisher's policy
    In this paper, the so-called added-mass effect is investigated from a different point of view of previous publications. The monolithic fluid–structure problem is partitioned using a static condensation of the velocity ...
