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.

压痕（刚度）

压痕试验是一种非常方便的方法来非破坏性地测量样品的机械性能。与需要从表面收获样品的无侧限压缩测试不同，压痕将样品的机械环境保持在感兴趣的位置及其与周围材料的相互作用。这允许重复测试。在该测试配置中，球形压头垂直于其表面压在样品上，同时记录施加的位移和产生的载荷。使用理论模型，可以从应力-应变曲线计算材料刚度。
