stress-strain curve
nounUK /strɛs streɪn kɜːv/
US /strɛs streɪn kɝːv/
A stress-strain curve is a line on a graph that shows how a material stretches and bends when you pull on it.
The engineer looked at the stress-strain curve to see how much the metal could stretch before it broke.
OTHER MEANINGS
2. A plot used in materials science to identify the elastic limit and ultimate tensile strength of a specimen.
The stress-strain curve revealed the steel's yield strength at about 250 MPa.
3. A graphical record from a tensile testing machine showing force versus deformation.
The lab printed the stress-strain curve right after the sample snapped.
4. A teaching tool for comparing how different materials like rubber and glass respond to pulling.
The teacher used a stress-strain curve to show why rubber stretches farther than glass.
