Analytic solution for two dimensional beam problems: Pure displacement boundary conditions
Baier-Saip, Jürgen; Baier, Pablo A.; de Faria, A. R.; Baier, H. (2024)The present manuscript delineates the derivation of strong solutions for the linear elasticity problem in a two dimensional rectangular beam. The materials under consideration can exhibit either isotropic or orthotropic ...

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 ...

Higher-order approximation to the guidewire model used in simulators of cardiac catheterization and multiple segment relaxations
Baier-Saip, Jürgen; Baier, Pablo A.; Oliveira, Jauvane C.; Baier, H. (2018)Cardiac catheterism is important because it offers many advantages in comparison to open surgery, for example, fewer injuries, lower risk of infections, and shorter recovery times. Simulators play a fundamental role in ...

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 ...

Layerwise theories for composite beams with continuous and discontinuous stresses
Baier-Saip, Jürgen; Baier, Pablo A.; de Faria, A. R.; Baier, H. (2023)Due to the unique characteristics of composite materials, the study of composite beams is far more complex than the study of homogeneous beams. The finite element method has proven to be a powerful approach to analyze ...

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 ...
