Hello everyone,

I am dealing with obtain a 2x2 Twill RVE element via material designer. However, I get confused with the term shown in question title.

What are the yarn volume fraction and yarn fiber volume fraction? In the "Material Designer User's Guide", there is a note such as:

"Note: The relationship between the fiber volume fraction, the yarn volume fraction, and the fiber yarn volume fraction is as follows: fiber volume fraction = yarn volume fraction * yarn fiber volume fraction." (Release 2021 R1 - page 54)


Thank you in advance
