Stress-strain Curve

Example in context

“The stress-strain curve for ductile steel shows a distinct yield plateau before strain hardening.”

“Sünek çeliğin gerilme-gerinim eğrisi, deformasyon sertleşmesinden önce belirgin bir akma platosu gösterir.”

Where engineers use it

Engineers use the stress-strain curve to identify material properties such as elastic modulus, yield strength, and ductility; it is essential for material selection and quality control in manufacturing.

Synonyms: stress-strain diagram, tensile curve

In Mechanical Engineering

A graph that shows the relationship between stress applied to a material and the resulting strain. It provides key mechanical properties such as yield point, ultimate strength, and elastic modulus.

“From the stress-strain curve of the aluminum sample, the yield strength was determined to be 280 MPa.”

In Materials Engineering

A graph plotting the stress carried by a specimen against the resulting strain during a mechanical test. Its shape reveals stiffness, yielding, hardening and the point of final fracture.

“Students learn to read the stress-strain curve so they can locate the elastic region, the yield point and the maximum load carrying stress.”

In Civil Engineering

A graphical representation showing the relationship between applied stress and resulting strain in a material. It is used to determine key mechanical properties such as yield strength, ultimate strength, and modulus of elasticity.

“The stress-strain curve of the concrete cylinder exhibited a brittle failure without a distinct yield plateau.”

Practice: can you use “Stress-strain Curve” at work?

A materials engineer is given tensile test data and must determine the Young's modulus and yield point from the stress-strain curve.
