General theory of second order isoparametric elements

  • Jean-Claude Sabonnadière

Abstract

The utilization of second order isoparametric finite elements is very common in specialized programs written for industrial application. A great deal of industrial equipment is composed of parts which are either straight lines or geometric curves and which can therefore be easily modelled by second order curves (circles, conic sections, etc). Except in extremely complicated geometry, modelling the phenomena with second order elements and the geometry with curvilinear elements, yields a high degree of accuracy with a reasonable number of elements.
