Subject fundamentals
This course operates as an hinge between the basic subjects (mathematics and physics) and the subjects taught in the following academic terms, which are oriented to design and applications. The goal of the course is to provide basical theoretical principles which, if well understood and applied, allows the student to analyse the mechanical behaviour of elastic solids and in particular of plane beam systems.
Expected learning outcomes
The student have to be able to determine the support reactions, tension, shear and bending diagrams and deflection curve for a statically determinate plane system of beams; to determine stress fields in a beam according to De Saint Venant's principle; to apply failure criteria in a triaxial state of stress; to verify a reinforced concrete beam under bending; to verify a slender column under compression.
Prerequisites / Assumed knowledge
The student have to know the kinematic, static and dynamic theory of the material point, vectorial operations (sum, scalar multiply, inner product, cross product), matrix operations, basic issues of linear algebra, analytic geometry, differential geometry. With reference to functions of one variable the students have to know the concept of limit, differentiation rules, integration rules, Taylor series and solution techniques of differential equations in case of constant coefficients. With reference to functions of several variables the students have to know differentiation rules, integration rules and Taylor series.
Contents
The basic topics of geometry of areas and of kinematics and statics of rigid body systems The mechanics of linear elastic solids −beams, plates, and three-dimensional solids− examined using a matrix approach. The analysis of strain and stress around a material point. The linear elastic constitutive law, with related Clapeyron's and Betti's theorems. Kinematic, static, and constitutive equations. The implication of the principle of virtual work. The De Saint Venant’s problem. The theory of beam systems, statically determinate or indeterminate. Methods of forces and energy for the examination of indeterminate beam systems. Elastic buckling of columns (Euler’s formula). Reinforced concrete beams under bending.

Assessment and grading criteria
The exam consists of a written test and an oral test. The written test is based on the solution of problems similar to those discussed during the practical classes. The themes developed from past exams are available through the website of the course.
The written test includes a statically determinate beam system, a statically indeterminate beam system, and the determination of principal axes of inertia and stresses in the section of a De Saint Venant solid. The oral test is based on two or three theoretical questions.
