CAREER: Research and Education on Deformation of Coated Materials

本学院早期教育发展（CAREER）项目的目标是促进对涂层材料变形的基本理解，并开发其加工技术。可变形涂层材料具有多种应用，从用于冲压的聚合物涂层金属板到用于柔性电子产品的金属薄膜涂层聚合物。在将涂层材料成型为有用产品的过程中，主要的挑战是保持涂层免受刀具接触损伤，以及在弹塑性变形过程中保持粘接。实现研究目标的方法是由实验和理论努力组成的多学科方法。具体来说，该研究将开发新的实验来提高对接触损伤和界面脱黏的理解。建模框架将基于涂层、基材和聚合物-金属界面的现象学描述和本构模型的发展。应用力学和粘附科学理论将结合设计新的涂层材料的制造技术。推进对涂层材料变形的认识将加速涂层新材料和涂层新工艺的发展。涂层材料的应用可以减少对环境的影响，降低制造成本。新的变形技术的发展将导致新产品的使能技术。CAREER项目将在课程开发、学生指导、工业合作和推广活动（如当地科学博物馆展览）方面进行各种努力。该项目将激发学生对知识发现过程的兴趣，并为学生应对未来的挑战做好准备。通过研究和教育的整合，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.
