This document discusses axisymmetric elements for finite element analysis. It covers the conditions required for a problem to be axisymmetric, including symmetry about the axis of revolution. It also discusses the derivation of shape functions for axisymmetric elements, such as the three node axisymmetric triangular element, and covers strain-displacement matrices, stress-strain relationships, and assembling the element stiffness matrix for axisymmetric elements.

- 6. UNIT – IV 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.
