Presets

Pull on a material and its stress-strain curve tells its story: a straight elastic region with slope equal to Young's modulus, a yield point where permanent deformation begins, a peak at the ultimate tensile strength, and finally fracture. Ductile metals stretch far; brittle ones like cast iron snap with almost no warning.

About this simulation

The full Stress-Strain Curve tool models a composite wing with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a composite wing?
Open this page and use the live Stress-Strain Curve tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a composite wing from your own measurements.
