 Subject fundamentals The course is subdivided into two main parts. The first part (SM) is related to the continuum mechanics, the theory of elasticity and to the calculus of civil and oil structures made of different materials (i.e. concrete and metal). The subject is addressed according to the most modern formulations, suitable for numerical implementation. The second part (PG) deals with the mechanical behavior of rock structures related to the oil and gas engineering. In particular this part is focused on the basic aspects of the stress strain behavior of rock material and rock masses and their interaction with fluids. Topics are discussed with reference to the reservoir geomechanics. Expected learning outcomes Ability to evaluate qualitatively and quantitatively the mechanical behaviour of man made (engineering works) and natural (rock masses) structures with reference to Oil and Gas Engineering and to adopt the proper approaches to the solution of specific engineering problems. Prerequisites / Assumed knowledge The basic concepts of Mathematics, Linear Algebra, Physics and Fluid Mechanics are required. Contents A. Calculus of one-dimensional structures I.
