INDENTATION (STIFFNESS)

An indentation test is a very convenient way to measure the mechanical properties of a sample non-destructively. Unlike the unconfined compression test, where a sample needs to be harvested from the surface, indentation maintains the mechanical environment of the sample at the location of interest and its interaction with the surrounding material. This allows the test to be repeated. In this test configuration, a spherical indenter is pressed against the sample perpendicularly to its surface while the applied displacement and resulting load are recorded. Using a theoretical model, it is possible to calculate material stiffness from the stress-strain curve.

壓痕（剛度）

壓痕試驗是一種非常方便的方法來非破壞性地測量樣品的機械性能。與需要從表面收獲樣品的無側限壓縮測試不同，壓痕將樣品的機械環境保持在感興趣的位置及其與周圍材料的相互作用。這允許重復測試。在該測試配置中，球形壓頭垂直于其表面壓在樣品上，同時記錄施加的位移和產生的載荷。使用理論模型，可以從應力-應變曲線計算材料剛度。
