随着纳米科学技术的发展,薄膜材料被广泛的应用于各个领域。氧化钛纳米材料具有自清洁功能,这使得纳米氧化钛涂膜被应用到建筑玻璃、卫生间以及厨房的装修材料中。但是薄膜材料的力学性能评价非常的复杂,目前大部分的研究是通过实验来完成,氧化钛薄膜力学性能对实验设备要求非常高,并且实验周期大,人力物力资源消耗大。在这种背景下,本文提出了一种氧化钛涂膜玻璃的纳米物理压痕有限元数值模拟方法,运用ANSYS软件在计算预处理模块建立了氧化钛涂膜玻璃和硬质接触头的数值模型,并通过网格划分将模型划分成8万个结构化六面体网格。最后,通过计算得到了不同厚度下氧化钛涂膜玻璃的弹性模量和硬度,其中弹性模量最大为91 GP,硬度最大为7.6 GP。
With the development of nano science and technology, thin film materials are widely used in various fields. Titanium dioxide nanomaterials have a self-cleaning function, which allows them to be used in architectural glass, bathroom and kitchen finishes. However, the evaluation of the mechanical properties of the thin film material is very complicated. At present, most of the research is done through experiments. The mechanical properties of the titanium oxide film require very high requirements on the experimental equipment, and the experimental period is large, which consumes a great amount of human and material resources. In this context, this paper presents a nano-physical indentation titanium oxide coated glass finite element numerical simulation method using ANSYS software in the calculation of the pretreatment module to establish a titanium oxide coated glass and hard contact numerical model , And divide the model into 80,000 structured hexahedral grids by meshing. Finally, the elastic modulus and hardness of titanium oxide coated glass under different thickness were calculated, the maximum elastic modulus was 91 GP and the maximum hardness was 7.6 GP.
