The Stress Strain Curve for FRP

Frida Ghitis: I think everyone was really familiar with the stress strain curve, let's say for steel and that drives into ductility. What does that look like for FRP? She says it doesn't have a yield. Being that it's a resin material with glass fibers, those glass fibers are a brittle substance. Once you reach the material rupture, it ruptures. There is no plateau, there's no strain hardening, it's more or less linear elastic to rupture. But just that initial portion of the stress strain Curve for steel is where we kind of live.Ghitis: Are you using because it's a little less ductile or prone to yielding? Do we
