Deformation Measurements at the Submicron Level Related to the Mechanics of Materials

将设计和建造一台扫描隧道显微镜，用于测量多相材料在纳米范围内的表面位移。这一结果对于改进和指导复合材料界面断裂的力学建模具有重要意义。首先将研究聚合物基和石墨纤维的复合材料以及金属的粘接，随着技术的改进，陶瓷和金属基复合材料中界面的变形和断裂行为的研究也应该是可能的。

A scanning tunneling microscope will be designed and constructed for measuring surface displacements in the nanometer range in multiphase materials. The results are particularly needed for improving and guiding mechanics modeling of interfacial fracture in composite materials. Initially composites of polymer matrix and graphite fibers, as well as adhesive bonding of metals will be examined, and as the technique is refined the study of the deformation and fracture behavior of interfaces in ceramics and metal based composites should also be possible.
