    This work presents a two-scale homogenization procedure to analyze three dimension composite structures by FEM. The theory implemented is compared with other micro-structural formulations: micro models and serial parallel ...
  • Numerical simulation of failure involving multiple cracks with smoothed displacements. 

    Olm Serra, Marc (Universitat Politècnica de Catalunya, 2013-05-13)
    Minor thesis
    Open Access
    To numerically simulate a failure process, damage models can be used. In order to avoid mesh dependency problems of local damage models, nonlocal models are employed. The use of nonlocal displacements is an efficient ...
  • Strain localization and failure mechanics for elastoplastic damage solids 

    Wu, Jian-Ying; Cervera Ruiz, Miguel (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
    Book
    Restricted access - publisher's policy
    This work investigates systematically strain localization and failure mechanics for elastoplastic damage solids. Two complementary methodologies, i.e., traction-based discontinuities localized in an elastic solid and strain ...
  • Structural system identification of cable-stayed bridges with observability techniques 

    Lozano Galant, Jose Antono; Nogal Macho, María; Payá Zaforteza, Ignacio Javier; Turmo Coderque, José (2014)
    Article

    Cable-stayed bridges are highly statically redundant, light and flexible structures. This complexity highlights the role of the structural system identification (SSI) method in the calibration of the actual properties of ...
