Abstract A systematic and critical review about the propagation of uncertainties related to the Depth Sensing Indentation data analysis standard procedures and its effect on the estimation of Young´s modulus of materials is reported. Uncertainties related to experimental issues like calibration of indenter area profile and determination of effective applied force and their propagation in estimating the indenter-sample reduced elastic modulus were discussed. On the other hand, theoretical uncertainties related to the contact mechanics fundamentals used for calculating the Young´s modulus of materials by using experimentally determined reduced elastic modulus in indentation experiments were also discussed. Theoretical uncertainties associated to assume fixed values for the mechanical properties of the indenter (Poisson´s ratio and Young´s modulus) and sample (Poisson´s ratio) to estimate the sample Young´s modulus were studied. In general, all the results suggest the experimental uncertainties are the main source of error in estimating the sample Young´s modulus, however the uncertainties associated to theoretical procedures can be comparable with them in some cases.

关于深度传感压痕数据分析中方法学不确定性的传播：简要而批判性的回顾

摘要 报告了与深度传感压痕数据分析标准程序相关的不确定性传播及其对材料杨氏模量估计的影响的系统和批判性审查。讨论了与实验问题相关的不确定性，例如压头区域轮廓的校准和有效施加力的确定及其在估计压头样品减少的弹性模量中的传播。另一方面，还讨论了与通过在压痕实验中使用实验确定的减少弹性模量来计算材料的杨氏模量的接触力学基础相关的理论不确定性。研究了与假设压头机械性能（泊松比和杨氏模量）和样品（泊松比）的固定值相关的理论不确定性，以估计样品的杨氏模量。一般而言，所有结果都表明，实验不确定性是估计样本杨氏模量的主要误差来源，但在某些情况下，与理论程序相关的不确定性可以与它们相比较。
