In modern times the finite element method has become established as the universally accepted analysis method in structural design. The method leads to the construction of a discrete system of matrix equations to represent the mass and stiffness effects of a continuous structure. The matrices are usually banded and symmetric.

Die Bewegungen der Kontinuumsmodelle aus den Kapiteln 2 und 4 werden durch partielle Differentialgleichungen beschrieben, deren Losungen geometrischen und kinetischen Randbedingungen genugen mussen. Eine analytische Losung der Gleichungen gelingt nur bei sehr einfachen Modellen und Randbedingungen.

Long before the contemporary concept of discretization used in the finite element method (FEM) appeared, so-called physical discretization (or physical lumping in English literature) methods were in active use. There, to solve a continual problem, a system with a finite number of degrees of freedom used to be introduced on the basis of certain physical

Finite Element Modelling of Sewer Linings
Civil-Comp Proceedings, 1997Abstract In the course of renovating egg-shaped sewer linings, comparisons of stress/strain and deflection levels with their permissible values are complicated not only by their shape but also by their considerably variable material properties and the choice of intermediate restraint set-ups.

A finite element model for the simulation of hydrometra
Technology and Health Care, 2004The behaviour of the human uterus under an internal (intracavital) pressure of 150 mm Hg (20 kPa) was modelled. The application of such an intracavital or intrauterine pressure corresponds to the procedure which is performed at the beginning of hysteroscopy (hydrometra).

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.

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
