  • Constitutive response and damage in solid propellants 

    Aravas, N.; Xu, F.; Sofronis, P.; Namazifard, A.; Fiedler, R. (2005)
    Solid propellants are composite materials with complex microstructure. In a generic form, the material consists of polymeric binder, ceramic oxidizer, and fuel particles (e.g. aluminum). Damage induced by severe stress and ...
  • Estimation of the prediction error correlation model in bayesian model updating 

    Simoen, E.; Papadimitriou, C.; Lombaert, G. (2013)
    In Bayesian model updating, probability density functions of model parameters are updated accounting both for the information contained in the data and for uncertainties present in the measurements and model predictions, ...
  • Fast Bayesian structural damage localization and quantification using high fidelity FE models and CMS techniques 

    Papadioti, D. C.; Papadimitriou, C. (2012)
    Bayesian estimators are proposed for damage identification (localization and quantification) of civil infrastructure using vibration measurements. The actual damage occurring in the structure is predicted by Bayesian model ...
  • Finite element model validation and predictions using dynamic reduction techniques 

    Papadioti, D. C.; Papadimitriou, C. (2011)
    Finite element (FE) model updating and validation techniques are formulated as single and multi-objective optimization problems. A multi-objective optimization framework results in multiple Pareto optimal models that are ...
  • Influence of the prediction error correlation model on Bayesian FE model updating results 

    Simoen, E.; Papadimitriou, C.; De Roeck, G.; Lombaert, G. (2012)
    Bayesian finite element (FE) model updating is a probabilistic method for uncertainty quantification in FE model updating, where the well-known Bayes' theorem is used to update probability density functions of model ...
  • On the inverse-Gaussian shadowing 

    Chatzidiamantis, N. D.; Sandalidis, H. G.; Karagiannidis, G. K.; Kotsopoulos, S. A. (2011)
    The Inverse Gaussian (IG) distribution has been recently proposed as a less complex alternative to the classical log-normal distribution to describe shadowing phenomena. This paper investigates the performance of digital ...
  • Optimal experimental design for structural health monitoring applications 

    Lam, H. F.; Papadimitriou, C.; Ntotsios, E. (2008)
    Successful structural health monitoring and condition assessment depends to a large extent on the sensor and actuator networks place on the structure as well as the excitation characteristics. An optimal experimental design ...
  • Structural damage identification using a Bayesian model selection framework 

    Papadimitriou, C.; Papadioti, D. C.; Ntotsios, E. (2010)
    A Bayesian model class selection and updating framework is used for identifying the location and size of damage in a structure utilizing measured dynamic data. The framework consists of a two-level approach. At the first ...
  • Thermodynamic investigation of the RbBr-TbBr3 system 

    Gong, W.; Wu, Y.; Chen, T.; Feng, S.; Gaune-Escard, M.; Jin, Z. (2010)
    The thermodynamic properties and phase diagram of the RbBr-TbBr3 system were analyzed by means of the CALPHAD method in this work. Thermodynamic models were defined in order to describe the Gibbs energies of the individual ...
