Subject aims expressed by acquired skills and competences

The course is focused on presentation of modern techniques of study of physical properties of geomaterials and their behavior in selected model conditions. Emphasis is placed mainly on mechanical properties and deformation response of studied materials in relation to their composition and structure or other physical characteristics. Student will get an overview of used physical methods and experimental techniques. They will acquire theoretical knowledge related to the design and preparation of mechanical tests of materials as well as special triaxial experiments. The graduate will acquire skills in analyzing experimental data from such experiments based on physical models. The acquired theoretical knowledge and analytical skills will be complemented by an appropriate form (actively or passively) within experiments carried out in the laboratories of the Institute of Geonics, AS CR.
