Course Aim: To impart knowledge on constitutive relations and failure of soils and rocks.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢    describe different stress-strain models of soils and to interpret soil behaviour accordingly.

➢    evaluate failure conditions of soil structures using limit theorems of plasticity.

➢    interpret the behaviour of soils using a critical state framework.

➢    describe stress-strain behaviour of rocks and explain discontinuities in rock masses.

Course Content:

➢    Stress-strain models: Elastic, non-linear, and anisotropic models

➢    Theory of plasticity: Yield criteria, hardening rule, flow rule, elasto-plastic models

➢    Limit analyses: Bound theorems of plasticity and applications

➢    Critical state soil mechanics: Cam-clay models of soil behaviour

➢    Stress-strain behavior of rocks: Mechanical and ultrasonic wave velocity methods

➢    Rock masses: Stress-strain behaviour of rock masses, stereographic projections
