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 ...

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 ...
