The project is aimed at establishing a synergistic link between Information Technology Research (ITR) and research in an emerging area of materials engineering. The research activities include the development of the multi-level theory of diffusion-induced deformation phenomena in particulate materials, such as sintering and electromigration. All constitutive relationships will be obtained through numerical experiments in a virtual test environment, using an innovative parallel computing procedure for linking different material structure levels. This will allow the reduction of a cumbersome and expensive experimental analysis and will clarify the sensitivity of material properties to different structure parameters at various length scales.The research efforts include a basis of an on-line process (powder consolidation) control for a wide range of particulate component designs, which are used in industries involved in the electronic circuits production for wireless applications, information technology devices, MEMS fabrication, sensors, etc. The project incorporates a plan for the advancement of the Materials Engineering Curriculum of San Diego State University, including the development of the Master of Engineering Program as well as the Joint Doctoral Program with University of California, San Diego.

该项目旨在建立信息技术研究（ITR）和材料工程新兴领域研究之间的协同联系。研究活动包括发展颗粒材料中扩散诱导变形现象的多层次理论，如烧结和电迁移。所有本构关系将通过虚拟测试环境中的数值实验获得，使用创新的并行计算程序连接不同的材料结构水平。这将减少繁琐和昂贵的实验分析，并将澄清材料性能对不同长度尺度下不同结构参数的敏感性。（粉末固结）控制，其用于涉及无线应用的电子电路生产，信息技术设备，MEMS制造，传感器等该项目纳入了圣地亚哥州立大学的材料工程课程的进步计划，包括工程硕士课程的发展，以及与加州大学圣地亚哥分校的联合博士课程。
