TWO DIMENSIONAL VECTOR VARIABLE
PROBLEMS
Axisymmetric Elements
In previous chapters, we have been concerned with one
dimensional elements and two dimensional elements. In this
chapter, we consider a special two dimensional element
called the axisymmetric element.
7. The required conditions for a problem to
be axisymmetric are as follows
The problem domain must be symmetric about the axis of
revolution, which is conventionally taken as the z axis.
All boundary conditions must be symmetric about the axis of
revolution.
All loading conditions must be symmetric about the axis of
revolution.
