9810978El-GizawyDescription: This award is for support of a cooperative project by Dr. Ahmed Sherif El-Gizawy, Director of the Industrial and Technological Development Center, College of Engineering at the University of Missouri in Columbia, and Dr. Amr Abdel-Hamid Professor and Dean of Science and Engineering at the American University of Cairo (AUC), in Cairo, Egypt. The two plan to build an integrated model that can describe quantitatively the process behavior during net shape fabrication of advanced aluminum structures. The proposed model consists of two modules: the physical and the numerical modeling modules. In the physical module, which will be handled by the US team, material constitutive equations are established and the process-structure-property relationships are determined. In the numerical module, to be developed by the AUC team, simulation of the entire net shape fabrication process will be conducted using the non-linear finite element code ABACUS. The integrated model can then be used with the robust design methodology to explore the optimum process parameters and product configuration that would maximize quality and minimize cost, while reducing waste and impact on the environment. The work will target the newly developed aluminum-copper-lithium alloy X2090 as a typical example of advanced material for use in various applications.Scope: This award will allow collaboration between Egyptian and US scientists who have complementary capabilities needed to carry out the proposed research efficiently. The model to be designed will be used with two manufacturing methods, the superplastic forming (SPF) and diffusion bonding (DB) for net-shape fabrication of complex multi-sheet structural components. Cost savings associated with this technique are based on high material utilization, reduced part count and the resulting assembly costs. The resulting alloys can provide the transportation industry (automotive and aircraft) with the capability of a cost-effective manufacturing process for large complex structures. The two collaborating teams are considered to be well qualified and experienced in the area of the research. This proposal meets the INT objective of increasing US-foreign collaboration in areas that benefit both sides. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities. ***

该奖项旨在支持哥伦比亚密苏里大学工程学院工业与技术发展中心主任Ahmed Sherif El-Gizawy博士与埃及开罗美国大学（AUC）科学与工程学院院长兼教授Amr Abdel-Hamid博士合作开展的一个项目。两人计划建立一个可以定量描述先进铝结构净形状制造过程行为的集成模型。该模型由物理模型和数值模型两个模块组成。在物理模块中，将由美国团队处理，建立材料本构方程，确定工艺-结构-性能关系。在由AUC团队开发的数值模块中，将使用非线性有限元代码ABACUS对整个净形制造过程进行模拟。然后，集成模型可以与稳健设计方法一起使用，以探索最佳的工艺参数和产品配置，从而最大化质量和最小化成本，同时减少浪费和对环境的影响。这项工作将以新开发的铝铜锂合金X2090为目标，作为各种应用中先进材料的典型例子。范围：该奖项将允许埃及和美国科学家之间的合作，他们具有有效开展拟议研究所需的互补能力。所设计的模型将采用超塑性成形（SPF）和扩散键合（DB）两种制造方法，用于复杂多片结构部件的净形制造。与此技术相关的成本节约是基于高材料利用率，减少零件数量和由此产生的组装成本。由此产生的合金可以为运输行业（汽车和飞机）提供具有成本效益的大型复杂结构制造过程的能力。这两个合作团队被认为在研究领域具有良好的资格和经验。该提案符合INT的目标，即在有利于双方的领域增加美国与外国的合作。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，以开展这些合作活动。＊＊＊
