Martin Diehl e3a64ae4ff don't fit close to 0K
cryogenic temperatures are normally not of interest, avoid considering
the strongly curved region below 80K in the fit gives probably better
extrapolation properties for T>300K
2022-02-13 14:57:01 +01:00
Martin Diehl ba16ea21a0 avoid overfitting
there are only 3 data points for C_13, with one close to 0K. Leave this
point out and fit only a 1st order polynomial

Martin Diehl 7e4a374c9e new material parameters
- 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.

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,
