Objectives

To provide students with formal theoretical knowledge and concepts of immediate application, capable of acquainting them with an integrated approach of Structural Geology problems and Rock and Soils Mechanics.

Program

I - Introduction: Origins and evolution of Geomechanics: The importance and necessity of study of this subject matter; fundamental concepts: terrain, mass, rock mass; classification of rocks and soils.

II- Formal instruments: index variables, vectors and tensor: Ricci and Einstein notation; operations of index variables; indexed variables of particular type; vectors; tensors; divergences and rotation of a vector; invariants; eigendirections; eigenvectors and eigenvalue; canonical form; isotope and tangential components; geometrical representations.

III- Stress and deformation analysis: concept of stress; stress tensor; conditions for stress components: equilibrium, displacement and finite deformation;

IV- Theory of regular behaviours: introduction; mechanical behaviour of homogeneous solid; fracture phenomenology; rheological models; Discretization;

V- Fracture, Disorder and the Theory of Critical Phenomena: Introduction, rupture criteria; simulation results; stochastic network models

VI- Elementary applications in mine extraction: study of undefined mass; stress distribution in free masses; stress in wells; stress in galleries; revetment dimensioning; types of revetment; fields of application.

Teaching methods and learning activities

There will be theoretical-practical and practical classes, being the last based on the illustration of the themes and concepts mentioned in theoretical-practical classes. It will take place a visit to a laboratory (INETI) during theoretical-practical classes.

Evaluation Type

Distributed evaluation without final exam

Eligibility for exams

- Regular attendance: attendance to classes according to the rules
- Tests and report on the visit to the laboratory
- Minimum average grade of 7 out of 20 in the assessment components

Calculation formula of final grade

- 3 individual tests - T (85% each)
- Report on the visit to the laboratory- R (15%)
- Final Grade: FG= T+R
- Completion of the course unit: FG=> 9.5 marks

Special assessment (TE, DA, ...)

According to General Evaluation Rules of FEUP
