Mechanics of Sandwich NanostructuresHanchen Huang and George Dvorak, Rensselaer Polytechnic InstituteThis project aims to determine the strain-structure relationship of a novel sandwich nanostructure. Based on self-organization, the Principal Investigator and his team have deposited Cu on SiO2 substrate. The Cu self-organizes into three layers: uniform 111 texture to porous 110 texture and back to uniform 111 texture, forming a novel sandwich structure with each layer being hundreds nanometers in thickness. Taking this sandwich structure as a prototype, the investigators will establish the strain-structure relationship by using a combination of atomistic simulations and multiscale micromechanics modeling. The scientific contribution of this project will be in the establishment of strain-structure relationship of nanoscale sandwich structures. The strain-structure relationship will enable one to design the sandwich structures (in terms of its layers thicknesses) and to apply it in various nanotechnologies. The broader impacts of this project include the education of graduate students, particularly those underrepresented, and the enrichment of graduate course Nanomechanics of Materials at RPI.

三明治纳米结构的力学Hanchen Huang 和 George Dvorak，伦斯勒理工学院该项目旨在确定新型三明治纳米结构的应变-结构关系。首席研究员及其团队基于自组织，将Cu沉积在SiO2衬底上。 Cu自组织成三层：均匀111织构到多孔110织构，再回到均匀111织构，形成每层厚度数百纳米的新型三明治结构。以这种夹层结构为原型，研究人员将结合原子模拟和多尺度微观力学建模来建立应变-结构关系。该项目的科学贡献将在于建立纳米级夹层结构的应变-结构关系。应变-结构关系将使人们能够设计夹层结构（就其层厚度而言）并将其应用于各种纳米技术。该项目更广泛的影响包括研究生的教育，特别是那些代表性不足的研究生，以及丰富 RPI 研究生课程“材料纳米力学”。
