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

9910345Oh 该奖项支持夏洛特北卡罗来纳大学 Hae-Soo Oh 博士和韩国大真大学 Sungjin Lee 博士之间为期 2 年的合作研究项目。 拟议的合作旨在对具有分层裂纹的纤维增强复合材料进行精确的应力分析。PI建议在微观层面和层压层层面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算法，该方法是 PI 之前与 I. Babuska 一起开发的。 由于纤维复合材料广泛用于各种行业的组件，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点近似所产生的基础研究问题。该提案提出了有效数值分析和纤维复合材料力学之间的跨学科活动。 该项目将与李博士在韩国的研究小组在美韩合作科学计划下共同进行，并将增强 PI 的美国研究生的国际经验。 该项目与美韩合作科学计划的目标相关，该计划旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作来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.
