Isoparametric axisymmetric quadrilateral
For rotary bodies with rotary or non-rotary loading. The axis of rotation is $y.$
Nodes
The element has 4 to 8 nodes. Midside nodes may be omitted.
Each node has displacements $[u,v]$ and temperature $[T].$
Faces (Edges)
The element has 4 edges, which are (considering the nonzero thickness) regarded as faces. Face normals point outward from the element.
| Face number | Node order |
|---|---|
| 1 | 1 – (5) – 2 |
| 2 | 2 – (6) – 3 |
| 3 | 3 – (7) – 4 |
| 4 | 4 – (8) – 1 |
