Deformation of Engineering Materials Across length and time Scales (DEMAS)

点击翻译按钮获取中文摘要

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.
