摘要 本文介绍了 Riedel 和 Blug (2001) 中总结的固态烧结模型的一些修改，并展示了其在模拟复合材料结构共烧结引起的变形中的应用。通过在粘度中引入额外项来考虑由于烧结早期阶段的重排而导致的致密化。使用有限元方法对层状薄结构进行详细分析，并将结果与厚基板上薄层情况的各种分析近似值进行比较。另外两个例子显示了该模型对实际情况的适用性。
Abstract This article presents some modifications of the solid state sintering model summarised in Riedel and Blug (2001) and shows its application for the simulation of distortions due to co-sintering of composite structures. The densification due to rearrangement in the early stage of sintering is taken into account by introducing an extra term in the viscosity. Detailed analyses of a layered thin structure are conducted with the finite element method and the results are compared to various analytical approximations for the case of a thin layer on a thick substrate. Two more examples show the applicability of the model to cases of practical interest.
