  • Cyclic constitutive model for concrete 

    Sima Brum, José Fernando; Roca Fabregat, Pedro; Molins i Borrell, Climent (Elsevier, 2008)
    Article
    Open Access
    A constitutive model for concrete subjected to cyclic loadings in both compression and tension is presented. The proposed model is intended to provide improvements on modelling the cyclic behaviour of concrete structures ...
  • Finite element analysis of compressive failure in stiffened carbon fiber panels 

    Torrent Collell, Jordi (Universitat Politècnica de Catalunya, 2011-09-29)
    Master thesis
    Restricted access - author's decision
    The use of composite materials in the aerospace industry is experiencing a large increase in recent years. Mainly they are used to build commercial aircraft fuselages. COCOMAT project had aimed to study and to improve ...
  • Microplane model M7 for plain concrete. I: Formulation 

    Caner, Ferhun Cem; Bazant, Zdenek Pavel (American Society of Civil Engineers (ASCE), 2013-12-01)
    Article
    Restricted access - publisher's policy
    Mathematical modeling of the nonlinear triaxial behavior and damage of such a complexmaterial as concrete has been a long-standing challenge in which progress has been made only in gradual increments. The goal of this ...
  • Numerical modelling of masonry shear walls failure mechanisms 

    Drougkas, Anastasios; Pelà, Luca; Roca Fabregat, Pedro (2014)
    Conference report
    Restricted access - publisher's policy
    This paper presents an investigation on the ability of two alternative FE-based numerical methods to simulate the in-plane strength and collapse of brick masonry shear walls. The methods considered consist of a meso-model, ...
  • Phase transformation and subsurface damage in 3Y-TZP after sandblasting 

    Chintapalli, R.K.; García Marro, Fernando; Jiménez Piqué, Emilio; Anglada Gomila, Marcos Juan (2013-05)
    Article
    Restricted access - publisher's policy
    Objective The goal of this work is to investigate t–m phase transformation, and subsurface damage in 3Y-TZP after sandblasting. Methods Commercial grade 3Y-TZP powder was conventionally sintered and fully dense ...
  • Plastic damage model for nonlinear reinforced concrete frames analysis 

    Faleiro de Freitas, Jeovan; Barbat Barbat, Horia Alejandro; Oller Martínez, Sergio Horacio (2005)
    Conference report
    Open Access
    This paper describes an improved analytical model for predicting the nonlinear response of multistory reinforced concrete frames, based on the concepts of isotropic continuum damage mechanics combined with plasticity theory. ...
  • Probabilistic assessment of seismic risk in urban areas 

    Aguilar, Armando; Pujades Beneit, Lluís; Barbat Barbat, Horia Alejandro; Ordaz Schroder, Mario Gustavo (2008-01-31)
    Conference report
    Restricted access - publisher's policy
    A probabilistic approach to estimate the expected seismic physical damage of existing buildings in urban areas is presented. The main steps of the procedure are seismic hazard, vulnerability and structural response. These ...
