Is the Stress-Strain Curve a Lie? (Engineering vs. True Stress)

If you are an engineering student, you have memorized the standard Stress-Strain curve. You know it goes up, peaks at the Ultimate Tensile Strength, and then drops down until fracture. But what if I told you that the "drop" in the curve is a convenient fiction? In this video, we uncover the Whole Truth about material behavior. We explore why the standard engineering curve looks the way it does, what is actually happening inside the material during Necking, and why the material is getting stronger even when the curve says it's getting weaker.
