Rationale

The tensile test is the gold standard for determining the yield strength and ultimate tensile strength of metallic materials. The tensile test typically requires machining of a large test coupon and a universal mechanical test machine. These requirements mean that tensile testing can often be slow and large sample volumes are required, which makes this method expensive due to the large amount of powder required, the printing time and sample machining. In addition, it is very difficult to map spatially-varying properties across a part. In some cases, such as complex parts made by additive manufacturing, it can be difficult if not impossible to produce a sample where properties can be reliably measured using conventional tensile testing. This standard for Indentation Plastometry is therefore required to establish a standardised test method for applying indentation-based tests (coupled with inverse finite element analyses) to accurately determine tensile properties.
