What modulus to use - TANGENT OR SEECANT modulus ?
What modulus to use - TANGENT OR SEECANT modulus ?
(OP)
Is there any guidelines on when the tangent and when the secant modulus should be used in modeling ? I am modeling fabric material so the behavior is non-linear but several people at my office think tangent modulus should be used whereas others think secant modulus should be used in modeling behavior.
I searched the web and nothing provides direction on what is more suitable for FEA non-linear fabric material behavior.
Thanks for any input.

Is this bare fabric? composite?
