Corso:
Second cycle degree programme (LM) in
Physics (cod. 9245)
Also valid for Second cycle degree programme (LM) in Physics of the Earth System (cod. 8626)
Learning outcomes
At the end of the course the student will possess a solid background in continuum mechanics, the basic concepts of tensor algebra, the main properties of the strain and stress tensors and the constitutive relationships of elastic materials, their use to describe elastic waves, the state of stress within the Earth, faulting and intrusion processes. In particular, the student will be able - to distinguish and characterize the stress regimes present in different regions of the Earth - to solve 2-D dislocation problems .
Course contents
The course is organized into two moduli, each dealing with different subjects within the following list.
Mechanics of continuum media. Stress and strain. Conservation laws. Thermo-Elastic materials. Elastic and adiabatic moduli.
Isotropic elastic media. Constraints on elastic moduli. Equations of motion (Cauchy-Navier). Elastic waves.
Stress within the Earth, theories of faulting. Elastostatic problems in a half-space: the Airy stress function.
Potentials in the theory of elasticity. Elastic dislocations and their representation.
Darcy's law and poroelasticity.
Readings/Bibliography
Lecture notes (Prof. Maurizio Bonafede) and slides will be available online (Insegnamenti online IOL).
Teaching methods
Classroom lectures and tutorials
Assessment methods
Oral examination: typically 3 questions are proposed to assess the
student's theoretical knowledge of the Mechanics of elastic solids
and its application to the study of the interior of the Earth. The
candidate is likely to be requested both to prove the main
theoretical results and to estimate some of the physical parameters
of the Earth interior.
