Abstract: 
Yttria-stabilized tetragonal-zirconia polycrystals (Y-TZP) have been shown to have superplastic properties at high temperatures, opening a way for the manufacture of complex pieces for industrial applications by a variety of techniques. However, before that is possible, it is important to analyze the deformation and fracture mechanisms at a macroscopic level based on continuum theory. In this paper, an elastic-plastic material model with a theoretical large deformation is constructed to simulate the true stress-true strain relationships of superplastic ceramics. The simplified constitutive law used for the numerical simulations is based on piecewise linear connections at the turning points of different deformation stages on the experimental stress-strain curves. The finite element model (FEM) is applied to selected tensile tests on 3-mol%-Y-TZP (3Y-TZP) co-doped with germanium oxide and other oxides (titanium, magnesium, and calcium) to verify its applicability. The results show that the stress-strain characteristics and the final deformed shapes in the finite element analysis (FEA) agree well with the tensile test experiments. It can be seen that the FEM presented can simulate the mechanical behavior of superplastic co-doped 3Y-TZP ceramics and that it offers a selective numerical simulation method for advanced development of superplastic ceramics.

This paper suggests a piecewise linear model to simulate the superplastic behavior of codoped Yttria-stabilized tetragonal-zirconia polycrystals. Though the 1D problem seems simple, there are certainly some difficulties needed to be overcome in the simulation.

超塑性Y-TZP基陶瓷之有限元分析

目的:通过调整非常精细的颗粒,四方晶氧化锆多晶(TZP)在室温下保持稳态四方相,并且具有优异的塑性。然而,当材料变形时,我们必须对超塑性陶瓷在机械应力分布和断裂机制方面有更多的理解。
创新点:1. 通过材料弹塑性模型;2. 使用胡克定律、塑性应变硬化及von Mises降伏准则;3. 结合等向性硬化规则及相关联的流动规则。
方法:1. 开发一个高温超塑性材料在不同应变率拉伸条件下具备不同应力-应变关系的组成律模型及有限元分析模型;2. 通过有限元法仿真模拟与实验结果比对;3. 验证所提方法的可行性和精确性。
结论:1. 有限元仿真模拟的应力-应变关系与实验数据吻合较好,对于所研究的四种组合物,最大应力和应变的误差均小于1%。2. 有限元仿真模拟的最终变形形状(宽度和厚度)与拉伸试验的结果一致;这些验证证实了所提有限元分析模型的可靠性。
