Material Model with Different Young Modulus in Tension and Compression
Material Model with Different Young Modulus in Tension and Compression
(OP)
Dears,
Is there a way to model a material with different Modulus of Elasticity (E) in tension and compression.
Anisotropic material properties gives the option of defining different E values in different directions.
How the different E values in Tension and compression can be defined for analysis of the materials having different properties/response in tension and compression.
Thanks for the input/help.

Cast Iron Young Modulus is also different in Tension and Compression, these values are easy to get for different types of cast iron as compare to Stress Strain curves.
Is there a way to do the elastic analysis with tow different E values (for Tension and Compression) only?

So it needs to be used with MP,EX command so if we try to be clever and set different compression stress strain data that would be a larger E mod, than tension and as set MP, then here is what we get, so not possible:
*** ERROR ***
For material 1 at temperature 20, the initial slope (4.E+11) of the
stress-strain curve based on the TB,UNIAXIAL table with option (COMP)
is greater than EX (2.E+11).
