DDIF2
brickThis page describes the DDIF2
brick.
The DDIF2
behaviour is used to describe the brittle nature of nuclear fuel ceramics (see [1–3]) and is usually coupled with a description of the viscoplasticity of those ceramics (See for example [6]).
The DDIF2
brick can be used in place of the StandardElasticity
brick. Internally, the DDIF2
brick is derived from the StandardElasticity
brick, so the definition of the elastic properties follows the same rules.
This brick is mostly a front-end to the DDIF2
stress potential. The reader may thus refer to this page for a complete description.
