Hello,

I am doing a simulation of a tensile test of a rectangular unidirectional carbon fiber composite. I am pulling one end of the rectangular piece and fixing the other end. I know how to get stress/strain and inverse reserve factor in the solution. What I would like to know is the strength of the composite; that is, the stress at which the composite fails. Another way to frame the question is that I would like to know the stress the moment the inverse reserve factor becomes greater than 1. How can I get this? 

Thanks in advance.
