2. Célkitűzések és tanulási eredmények
2.1 Célkitűzések
The aim of the course is that the students get to know the use of numerical methods that aid geotechnical and engineering geological design. The students get familiar with the advantages and disadvantages of analytical methods and applications of finite element methods to geotechnical and engineering geological problems using different commercially available software. The students get to know the special elements and material models that are typically used in the case of FE modelling of geotechnical problems. The students get to know the most frequently used rock mechanical methods for modelling fractured rocks.
