Finite element modelling of charged beams
IEEE Transactions on Magnetics, 1994Modelling of charged particle beams requires the solution of an electrostatic Poisson problem where the space charge density associated with the beam can be determined by means of iterative procedures coupling the field to the motion of the particles.

A finite element model of the otolith membrane
Computers in Biology and Medicine, 1977Abstract This paper describes a finite element model of the otolith membrane. The system of differential equations governing the displacement of the membrane is expressed in the equivalent variational form. The region occupied by the membrane is divided into triangles and the computer is used to determine the linear combination of the functions ...

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.

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.

This chapter covers the numerical modeling of carbon nanotubes based on the finite element method. The approach based on a three-dimensional space-frame structure where the bonds between carbon atoms are considered as connecting load-carrying generalized beam members, while the carbon atoms act as joints of the members, is introduced. The assignment of

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.

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.
