Aim(s)
To impart knowledge and understanding of stress-strain and failure behaviour of soils and rocks under static and dynamic conditions.
Intended Learning Outcomes
On successful completion of the course, the students should be able to; Describe different stress-strain models of soils and apply them to interpret real soil behaviour under static and dynamic conditions. Evaluate failure conditions of soil structures using limit theorems of plasticity. Interpret the behaviour of soils using critical state framework. Explain stress-strain behaviour of rocks and analyse geological structures
