Stress–Strain Curves
Investigate a failed bracket, run a virtual tensile test, and learn what a stress–strain curve can tell you about the material.
Begin the investigation →Learning through games
Game 01 · 5 challenges
Stress–strain lab
Make steel spring back, leave a lasting stretch, catch peak strength, and handle a brittle sample. Learn by playing with the curve.
