英文摘要: Due to the novel chemical and physical properties, Metal-Organic frameworks materials own attractive potential in many application fields. The mechanical property of Metal-Organic frameworks actually plays an important role in their practical applications. In this project, the theoretical calculation methods will be employed to study the elastic properties and the atomic evolution of non-elastic deformation of Metal-Organic frameworks. The effects of internal defects, grain boundary, guest loading and etc. on the mechanical properties of the bulks will be investigated. Therefore, the project will not only solve the scientific problems in this field, but also guide the practical applications of Metal-Organic frameworks. Finally, the project will develop the mechanical forming technology of Metal-Organic frameworks bulks.
