CAREER: Research and Education on Deformation of Coated Materials

该学院早期职业发展(Career)计划项目的目标是促进对涂层材料变形的基本了解，并开发其加工技术。可变形涂层材料有多种应用，从用于冲压的聚合物涂层金属薄板到用于柔性电子产品的金属薄膜涂层聚合物。将涂层材料制成有用产品的主要挑战是如何防止涂层与刀具接触损坏，以及如何在弹塑性变形过程中保持粘结力。达到研究目标的方法是一种多学科的方法论，包括实验和理论努力。具体地说，这项研究将开发新的实验，以提高对接触损伤和界面退粘的理解。建模框架将基于涂层、基材和聚合物-金属界面的唯象描述和本构模型的发展。将应用力学和附着力科学理论相结合来设计涂层材料的新制造技术。对涂层材料变形的深入了解将促进新涂层材料和新涂层工艺的发展。涂层材料的应用可以减少对环境的影响，降低制造成本。新变形技术的发展将使新产品的技术成为可能。Career项目将在课程开发、学生指导、产业合作和推广活动(如当地科学馆展览)方面做出各种努力。该项目将激发学生对知识发现过程的兴趣，并将使学生为迎接未来的挑战做好准备。通过研究和教育的融合，将开发新的智力资本。

The objective of this Faculty Early Caree Development (CAREER) Program project is to advance fundamental understanding of deformation of coated materials and to develop their processing technologies. Deformable coated materials have diverse applications, from polymer coated sheet metal for stamping to metallic thin film coated polymer for flexible electronics. The major challenges in forming coated materials into useful products are in keeping the coating from tooling contact damage and in maintaining the adhesive bond in the elastic-plastic deformation process. The approach toward the research objective is a multidisciplinary methodology that consists of both experimental and theoretical efforts. Specifically, the research will develop novel experiments to improve the understanding of contact damage and interface decohesion. The modeling framework will be based on the development of phenomenological descriptions and constitutive models of the coatings, substrates, and polymer-metal interface. Applied mechanics and adhesion science theories will be integrated to devise novel fabrication techniques for coated materials.Advancing the understanding of deformation of coated materials will accelerate the development of new coating materials and new coating processes. Application of coated material can lessen environmental impact and reduce manufacturing cost. Development of new deformation techniques will result in enabling technologies for new products. The CAREER project will undertake various efforts in curriculum development, student mentoring, industrial collaboration, and outreach activities such as local science museum exhibitions. The project will spark students' interest in the process of knowledge discovery and will prepare students to take on future challenges. Through the integration of research and education, new intellectual capital will be developed.
