U.S.-Korea Cooperative Science: Accurate Stress Analysis of Fiber-Reinforced Composite Material with Delamination Cracks

9910345 OhThis award supports a 2 years collaborative research project between Dr. Hae-Soo Oh，University of北卡罗来纳州，夏洛特和Dr. Sungjin Lee，Daejin University，韩国. 该合作项目旨在对含分层裂纹的纤维增强复合材料进行精确的应力分析。PI建议在微观和层合层两个层面上研究纤维复合材料的失效机制。 PI建议通过生成辅助映射方法来开发新的算法，PI以前与I一起开发了该方法。巴布斯卡 由于纤维复合材料大量用于各种行业的部件，因此研究其失效机制是一项重要的活动，它远远超出了涉及偏微分方程的数学模型中出现的奇异点近似所产生的基本研究问题。该提案建议有效的数值分析和纤维复合材料力学之间的跨学科活动。 该项目将与韩国的李博士小组一起在美国-韩国合作科学计划，并将加强PI的美国研究生的国际经验。 该项目与美国的目标有关-韩国合作科学计划，旨在通过科学信息、思想、技能和技术的交流，以及通过在互利问题上的合作，提高美国和韩国科学家和工程师之间的合作水平。

9910345OhThis award supports a 2-year collaborative research project between Dr. Hae-Soo Oh, University of North Carolina, Charlotte and Dr. Sungjin Lee, Daejin University, Korea. The proposed collaboration aims to conduct accurate stress analysis of fiber-reinforced composite materials with delamination cracks.The PI proposes to investigate the failure mechanisms of fibrous composites both at the micro-level and at the laminate level. The PI proposes to develop new algorithms by generating the Method of Auxiliary Mappings, which the PI developed previously together with I. Babuska. Since fibrous composites are heavily used for components in a wide variety of industries, investigating the mechanisms for their failure is an important activity, which extends well beyond the basic research questions arising in the approximation of singularities occurring in mathematical models involving partial differential equations. The proposal suggests an interdisciplinary activity between efficient numerical analysis and mechanics of fibrous composites. This project will be performed in conjunction with Dr. Lee's group at Korea under the U.S.-Korea Cooperative Science Program and will enhance the international experiences for the PI's U.S. graduate student. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program, which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
