Equivalent elasticity modulus
Equivalent elasticity modulus
(OP)
Thank you so much for reading this post, I hope you can help me with this topic.
I am reading a book where says something like: "The elasticity modulus of material A is EA GPa, the elasticity modulus of material B is EB GPa. So, assuming that both materials are X% on the piece, the resultant one is E". On the book the values that appear are 110GPa and 3GPa, so the final result is 9.4GPa with 50% of each material.
Does anyone know how is this calculated?
Thanks a lot!

RE: Equivalent elasticity modulus
Is the 50% by weight or by volume? I believe the calculation is generally:
E = VaEa + (1-Va)Eb, but that comes out closer to 57GPa. If you add some percentage for void, it will drop. Check out http
RE: Equivalent elasticity modulus
I have been searching on the internet and it seems there is a formula from Enst which is used tocalculate it. But I haven't found this formula.
Thanks for helping, and hope better luck next time.

I will try to do with volumes, but I am not sure wether it will work or not.
As soon as I have it done I will tell you.
Thanks!
