  • Approximate artery elasticity using linear springs 

    Baier-Saip, Jürgen; Baier, Pablo A.; Schilling, Klaus; Oliveira, Jauvane C. (2017)
    The mechanical properties of arteries play an essential role in the study of the circulatory system dynamics, which has been becoming increasingly important in the treatment of cardiovascular diseases. Similarly, when ...

  • Hysteresis in the rhombohedral–orthorhombic phase transition of KNbO3 under inhomogeneous strain 

    Baier-Saip, Jürgen; Cabrera, A. L.; Baier, Pablo A.; Gutiérrez-Trujillo, Manuel (2013)
    The influence of the heating rate on the low temperature phase transition (PT) of the piezoelectric crystal potassium niobate (KNO) was studied by micro-Raman spectroscopy. It is found that crystallographic defects are ...

  • Linear spring stiffnesses for two-dimensional finite element modeling of arteries 

    Baier-Saip, Jürgen; Baier, Pablo A.; Oliveira, Jauvane C.; Baier, H. (2018)
    The physical properties of arteries are important in the research of the circulatory system dynamics. Moreover, in order to build Virtual Reality Simulators, it is crucial to have a tissue model able to respond in real ...

  • Shear locking in one-dimensional finite element methods 

    Baier-Saip, Jürgen; Baier, Pablo A.; de Faria, A. R.; Oliveira, Jauvane C.; Baier, H. (2020)
    The accuracy of the results obtained with Finite Element Methods depends on the basis functions employed to approximate the displacement fields. If the beam is very thin, there can be shear locking and the numerical ...

  • Simulator for minimally invasive vascular interventions: Hardware and software 

    Baier-Saip, Jürgen; Baier, Pablo A.; Schilling, Klaus (2016)
    In the present work, a simulation system is proposed that can be used as an educational tool by physicians in training basic skills of minimally invasive vascular interventions. In order to accomplish this objective, ...

  • Surfaces for modeling arteries in virtual reality simulators 

    Baier-Saip, Jürgen; Baier, Pablo A.; Srinivasan, L.; Voelker, W.; Schilling, Klaus (2015)
    We propose a surface model that can be used as part of an internet based educational medical simulator to train physicians in cardiovascular interventions. This is the first step towards building a real device which can ...
