Tensile Testing

What this topic covers

Strength, yield, elongation and stress-strain behaviour under controlled tension.

Core testing ideas

A tensile specimen is loaded in tension while force and extension are measured.

Results can include yield strength, ultimate strength and elongation depending on the method.

Machine operation, specimen dimensions and test rates must follow applicable procedures.

Measurement and method limits

Specimen orientation, preparation, environment and test rate can affect results.

Evidence and traceability

Destructive tests are valuable because they directly measure behaviour, but tested specimens are consumed or altered.

Using the result

Component design decisions require engineering interpretation beyond a laboratory property value.
