We carried out a residual stress distribution analysis in a APS TBC throughout the depth of the coatings. The samples were heat treated at 1150 °C for 190 h and the data analysis used image based modelling based on the real 3D images measured by Computed Tomography (CT). The stress distribution in several 2D slices from the 3D model is included in this paper as well as the stress distribution along several paths shown on the slices. Our analysis can explain the occurrence of the "jump" features near the interface between the top coat and the bond coat. These features in the residual stress distribution trend were measured (as a function of depth) by high-energy synchrotron XRD (as shown in our related research article entitled 'Understanding the Residual Stress Distribution through the Thickness of Atmosphere Plasma Sprayed (APS) Thermal Barrier Coatings (TBCs) by high energy Synchrotron XRD; Digital Image Correlation (DIC) and Image Based Modelling') (Li et al., 2017) [1].
我们对大气等离子体喷涂（APS）热障涂层（TBC）整个涂层深度范围内的残余应力分布进行了分析。样品在1150℃下热处理190小时，数据分析采用基于计算机断层扫描（CT）测量的真实三维图像的基于图像的建模方法。本文给出了三维模型中几个二维切片的应力分布以及切片上所示几条路径的应力分布。我们的分析可以解释顶涂层与粘结层界面附近“跳跃”特征的出现。通过高能同步辐射X射线衍射测量了残余应力分布趋势中的这些特征（作为深度的函数）（如我们的相关研究文章《通过高能同步辐射X射线衍射、数字图像相关（DIC）和基于图像的建模理解大气等离子体喷涂（APS）热障涂层（TBC）厚度范围内的残余应力分布》所示）（Li等人，2017年）[1]。
