- austenitic steel AISI304
- SAE1050 after quenching to martensite
I don't know how the old set of elastic constants for martenstite
(originally coming from 10.1088/0965-0393/23/4/045005) was derived,
but it is hard to believe that the elastic behavior can be that strongly
modified by a heat treatment.
- ort not tested, no examples, no documentation => removed
- aP is the opposite of isotropic => removed
isostropic materials can be easily specified as cI or cF, using C_44 =
1/2 * (C_11 - C_12). Acceptable extra effort for special use case
orthorhombic can be easily implemented if needed, but needs test,
documentation, and examples
