Eight-node brick element with reduced integration (C3D8R and F3D8R)

The C3D8R element is a general purpose linear brick element, with reduced integration (1 integration point). The shape functions are the same as for the C3D8 element and can be found in [33]. The node numbering follows the convention of Figure 43 and the integration point is shown in Fig 45.

Due to the reduced integration, the locking phenomena observed in the C3D8 element do not show. However, the element exhibits other shortcomings:

The F3D8R element is the corresponding fluid element.
