Modelling the arterial wall by finite elements
Archives Internationales de Physiologie, de Biochimie et de Biophysique, 1993The mechanical behaviour of the arterial wall was determined theoretically utilizing some parameters of blood flow measured in vivo. Continuous experimental measurements of pressure and diameter were recorded in anesthetized dogs on the thoracic ascending and midabdominal aorta.

A FINITE ELEMENT MODEL FOR ACOUSTIC RADIATION
Journal of Sound and Vibration, 1998Summary: An extension of the finite element technique to the analysis of the acoustic radiation is presented. In the proposed approach, the acoustic domain is split into two parts by an arbitrary artificial boundary enclosing the radiating surface. Then the unbounded medium is discretized with finite elements consisting of only one or two rows in the ...

Computational Modeling and Finite Element Analysis
SPINE, 2016Computational modeling with finite element analysis (FEA) is an integral component of medical device design and development. Researchers assess dimensions and stability of the experimental device; test load sharing, stresses, and strains; and analyze failures and modifications. The most important step in FEA is validation of the model.

Many structures of practical importance are too complex to be analyzed by classical, analytical techniques and, hence, numerical analysis is generally used. The finite element method is the most widely used numerical technique for structural and system analyses.

Finite element modelling with transformation techniques
IEEE Transactions on Magnetics, 1999Transformation methods are a very powerful tool in finite element modelling. In many cases, an adequate mapping transforms the problem into an easier one or allows advantage to be taken of the symmetries. This paper demonstrates that any mapping can be handled automatically provided the classical vector analysis approach is given up for the benefit of ...

The finite element method is nowadays the standard method for solving partial differential equations, especially in continuum mechanics. In this chapter the fluid, solid and interface elements are derived. The elements are employed for the discretization of the nearfield, that is the dam, the nearfield of the foundation and the nearfield of the ...

Modelling Rivets in the Finite Element Analysis
SAE Technical Paper Series, 2007<div class="htmlview paragraph">Riveting is a well established technology in the manufacturing of aeronautical structures as well as in the automotive industries. Despite its simplicity, the rivet presents a local stiffness that is not easy to properly model within a large finite element analysis.
