Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Attribute Development Method Attribute Developed
The students will develop the ability of formulating mathematical solutions to Geomechanics and geotechnical problems, as well as using computer software to solve such problems and critically appraise the quality of the analytical framework underlying the solution. Design (Level 3)
The student will develop an in-depth knowledge of state-of-the-art numerical methods, (finite element method, the finite differences method, discrete element method etc.), their strengths and limitations as they apply to problems of Geomechanics and geotechnical engineering. Engineering/IT Specialisation (Level 4)
Students will be required to communicate the findings of all their assignments in writing and those of at least one assignment as a verbal presentation. This will contribute to the development of their communication skills. Communication (Level 3)
At least one assignment will be conducted as group work and will hence contribute to developing the teamwork ability of students. Project and Team Skills (Level 2)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table.

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

Design (Level 3)
1. Critically appraise the strengths and limitations of the various numerical techniques listed under point 4, as they apply to the solution of Geomechanics problems.
2. Use computer software to solve mechanical and hydrological problems in Geomechanics and critically appraise the quality of the solutions obtained.
3. Identify and characterise problems where coupling between mechanical and hydrological fields occurs, conditions under which coupling is important, as well as ways of assessing the strength of coupling.
Maths/Science Methods and Tools (Level 4)
4. Critically appraise the strengths and weaknesses of experimental vs numerical investigations of Geomechanics problems and the design of geotechnical engineering solutions.
5. Derive the mathematical formulation for a numerical algorithm such as finite difference or finite element method to solve mechanical and hydrological problems in Geomechanics.
6. Derive the mathematical formulation for a numerical algorithm such as finite difference or finite element method to solve consolidation problems in Geomechanics.
7. Understand the fundamentals of other numerical techniques not covered in learning outcomes 2 or 3 (finite difference method, finite element method, discrete elements method).
