The proposed program aims to study deformation of engineering materials across length and time scales. The long term objective of this research program is to be able to assess and enhance structural integrity and performance of the metallic and non-metallic composites used in three strategic industries: nuclear, aerospace, and transportation. The materials that are used in these industries are very often exposed to hostile environments while carrying mechanical loads. In such environments, materials deform reversibly (elastically) or irreversibly (plastically). Plastic deformation can potentially localize at particular points in engineering components and subsequently lead to crack nucleation and catastrophic failure.

拟议的计划旨在研究工程材料在长度和时间尺度上的变形。该研究计划的长期目标是能够评估和增强核、航空航天和交通运输三个战略行业中使用的金属和非金属复合材料的结构完整性和性能。这些行业中使用的材料在承受机械负载的同时经常暴露在恶劣的环境中。在这种环境中，材料会发生可逆（弹性）或不可逆（塑性）变形。塑性变形可能集中在工程部件的特定点，随后导致裂纹成核和灾难性故障。
