Abstract Analysis of the effective properties and elastic stress field in two-scale composite ceramics as mechanical properties analyzer can be a daunting task to handle. Here, we address the most prominent hurdles, namely, the complex structure characteristics of dual-scale multiphase ceramics. We propose two-scale matrix-inclusion model and conducts the mechanical properties analysis of two types of scale interfaces to improve calculation accuracy. Our model estimates the different field at the nano-interface under different applied loadings, along with the considering on continuous condition of stress and displacement at nano-interface and the condition of far-field stress-strain. We show how to solve the problem of solving the elastic field of a thin interface layer into a problem of solving the incompletely combined interface elastic field under different conditions, analyzing the slip stress field of the meso-contact interface under longitudinal and transverse shear.

二维复合陶瓷的有效性能和弹性应力场

摘要 作为力学性能分析仪，对二尺度复合陶瓷的有效性能和弹性应力场进行分析是一项艰巨的任务。在这里，我们解决了最突出的障碍，即双尺度多相陶瓷的复杂结构特征。我们提出了两尺度矩阵包含模型，并进行了两种尺度界面的力学性能分析，以提高计算精度。我们的模型估计了在不同施加载荷下纳米界面处的不同场，同时考虑了纳米界面处应力和位移的连续条件以及远场应力应变条件。
