In partnership with General Motors Research and Development Center (GM), this research will build and validate a novel spectral framework for delivering process design solutions. The new framework for process design will build on recent advances made in the PI's research group in efficient spectral representations of microstructure-property-processing linkages. This spectral approach, known as Microstructure Sensitive Design (MSD), employs a statistical description of the microstructure and facilitates consideration of the microstructure simply as a point that lies inside a well defined convex hull in an appropriate Fourier space. Microstructure evolution during a selected manufacturing process will then be treated as a pathline in the same space. The efficiency of the method promises to provide the previously unattainable goal of a searchable and complete space of microstructures and paths required for process design. This work addresses an important strategic need for the US manufacturing industry, and will allow this industry to benefit directly from the emerging Materials Design methodologies and become globally competitive. The proposed interdisciplinary activity also brings together expertise from several traditional fields including mechanical engineering, manufacturing science, engineering design, materials science, and applied mathematics. This will have a significant impact on the development of skilled human resources in emerging science and advanced technology fields.

与通用汽车研发中心（GM）合作，该研究将建立和验证一个新型的光谱框架，以提供过程设计解决方案。过程设计的新框架将基于PI研究小组在微观结构 - 普罗沃处理链接的有效光谱表示方面的最新进展。这种光谱方法（称为微结构敏感设计（MSD））采用了微观结构的统计描述，并促进了对微结构的考虑，仅作为在适当的傅立叶空间中定义明确的凸船体内的点。然后，在选定的制造过程中的微观结构演变将被视为同一空间中的途径。该方法的效率有望提供以前无法实现的目标，即过程设计所需的微观结构和路径的完整空间。这项工作解决了美国制造业的重要战略需求，并将使该行业直接从新兴材料设计方法中受益并在全球范围内受益。拟议的跨学科活动还汇集了几个传统领域的专业知识，包括机械工程，制造科学，工程设计，材料科学和应用数学。这将对新兴科学和先进技术领域的熟练人力资源的发展产生重大影响。
