| Students get familiar with the Finite Element Method, the currently dominant tool for numerical modeling in geotechnics. Emphasis is placed on introducing the basic principles of the Finite Element Method and their subsequent application to selected problems of Geotechnical Engineering. The course summarises the types of finite elements used in geotechnical applications, material models suitable for the description of ground deformation, and selected specifics associated with numerical modeling in geotechnics. This knowledge is further applied in the modelling of foundation, embedded walls, and stability problems. |
