| Abstract Scope |
PIP testing (https://doi.org/10.1002/adem.202100437) involves indentation of (metallic) samples, indent profile measurement and iterative FEM simulation, converging on the stress-strain relationship giving optimal agreement between measured and modelled profiles. A key feature is the scale. The deformed region has lateral dimension of ~1 mm and a depth of ~ 100 µm (requiring a load in the kN range). The tested volume is usually “many-grained”, and hence representative of the bulk, whereas most nano-indentation takes place within single grains. A systematic comparison (https://doi.org/10.1002/adem.202001496) has already confirmed the superior reliability of PIP, compared with nano-indentation-based techniques. The current work concerns (isotropic and homogeneous) AM materials, following an earlier PIP-based investigation (https://doi.org/10.2139/ssrn.3746800) into the anisotropy of AM samples. Comparisons are presented between the outcomes of PIP, a nano-indentation-based procedure and conventional tensile testing. It is clearly shown that PIP is particularly well-suited to characterization of AM components. |
