Abstract
Descriptively speaking, a finite element system is obtained by subdividing a nonrigid continuum into geometrically simple subdomains, which are connected at discrete nodes. A material law, such as Hooke’s law for linear-elastic material, then leads to internal forces and torques which are reflected in the stiffness matrix of a single finite element. The nodes of the elements are linked by means of holonomic constraints, and external forces and torques can also act upon the nodes. Many details concerning the finite element method can be found e.g. in Wriggers [67], Bathe [6], or Zienkiewicz and Taylor [68].
