摘要：本文介绍了有限元建模在工业失效分析和工程问题解决中的应用，重点关注高度集成电子元器件的精确表征以及医疗产品的质量控制。具体而言，本文引入了纳米压痕法，用于准确表征电子元器件中超薄膜或涂层的性质，以及用于评估心血管支架疲劳开裂的微观力学模型。这两种建模方案在机械性能评估（强度、硬度和疲劳寿命）方面提供了重要的参考，进而也对材料设计和工艺优化提供了支持。。本文从客户导向的角度进一步探讨了先进的建模策略。同时，本文介绍了综合建模框架和跨学科策略，以在工程行业提供更加可靠和有效的解决方案。
Abstract: This paper introduces finite element modeling applications in industrial failure analysis and engineering problem solving, with particular emphasis on characterization of highly integrated electronics, and quality control of medical products. Specifically, this paper introduces a nanoindentation approach to accurately characterize the properties of ultra-thin film or coating in electronics, and a micromechanical model for evaluating the fatigue cracking in cardiovascular stents. The two modeling solutions can be used as a reference for mechanical properties evaluation (strength, hardness, and fatigue life), which in turn, support material design and process optimization. Further insights into advanced modeling strategies are discussed from a client-focused perspective. The integrated modeling framework and interdisciplinary strategies are introduced, for reliable and effective solutions in the engineering industry.
