Learning Outcomes
At the end of the course the students will be able to:
• Plot stress paths and estimate pore water pressure for the most common stress states
• Estimate the characteristics of stress-strain behavior of soil, obtained from laboratory tests,
• Understand soil behavior before failure and at critical state and derive corresponding stresses and strains,
• Understand the importance of residual strength in the case of large soil deformation,
• Understand the relation between soil parameters and recognize the critical conditions for geotechnical design.
• Understand the basic principles of plasticity theory,
• Understand the basic principles of critical state theory,
• Use soil constitutive models to model the nonlinear behaviour of soils.
