Tensile testing

Testing method to determine a material's ultimate and yield strength by measuring how a test rod deforms under gradually increased tensile force.

Illustration of Tensile testing

The process

A specially designed test piece [1] is clamped at their ends to a tensile testing machine. The specimen is then pulled slowly out with increasing tensile force along its axis. As the rod is extended slowly a neck is formed at its center, and finally leading to failure. The machine records the current strain and tension and creates a stress-strain curve.

Specimens with predetermined standard measure is used.
