Finite Deformation Analysis of Manufacturing Processes

9612017 微观力学是研究材料的微观结构如何影响其微观响应的学科。 它为设计和初步分析提供了开发简化模型所需的理解。 目前，工业界使用微观力学的能力受到材料可用工具的限制。 为了便于理解，需要将微观力学理论与实验进行比较。 该研究通过先进的电子显微镜技术，图像处理技术和大规模/大规模并行非线性有限元方法的独特组合来解决这些问题。 代表性体积元（RVE）的分析被用来比较微观力学理论与实验。 微观结构的微观力学建模是与美国铝业公司的研究人员合作进行的。 这个项目在理论和实验之间取得了平衡。 与工业界的合作将确保研究问题得到切实解决。

9612017 Micromechanics is the study of how the microstructure of a material affects its microscopic response. It provides the understanding necessary to develop simplified models for design and preliminary analysis. Currently the ability of industry to use micromechanics is limited by the tools available for materials. To facilitate this understanding, means of comparing micromechanical theories to experiments is required. The research addresses these issues with a unique combination of advanced electron microscopy techniques, image processing technologies, and large scale/massively parallel nonlinear finite element methods. Analyses of the representative volume element (RVE) are used to compare micromechanical theories to experiments. The micromechanical modeling of the microstructures is conducted in collaboration with researchers at Alcoa. This project has a balance between theory and experiment. The collaboration with industry will ensure the research issues are realistically addressed.
