Tensile and Formability Testing

A variety of materials properties can be determined from a tensile test. The yield strength is the stress per unit area that a material can withstand before permanent deformation occurs. The ultimate tensile strength is the maximum stress per unit area that a material can withstand before rupture. Both materials properties, which are determined from a tensile test are used in design calculations as well as routine quality control.
Ductility is measured using elongation and reduction of area. Tensile and Formability Testing

The strain hardening test (n-value) and the plastic strain ratio (r-value) are used as measures of formability and are useful measurements for deep drawing or stretch forming applications.

The existence of hydrogen embrittlement damage can be determined with a static load tensile test. This test is commonly used to verify safe plating conditions were present when plating hardened steels.

Most tensile materials properties can be determined at temperatures ranging from -70°C to 200°C.Tensile and Formability Testing
