Tensile Test Data and Material Behavior

A stress-strain diagram shows how a material responds during a tensile test. It records the mechanical behavior of a cylindrical specimen as it is pulled by an increasing centric load. The specimen is carefully prepared before testing.

Consider a cylindrical specimen placed in a system to measure its tensile strength.

Two gauge marks are inscribed on the central portion of the specimen. The length between the marks is known as the gauge length.

Then, a tensile load is applied on both ends of the specimen.

As the load increases, the gauge length increases, ...
