Course description

The course is intended to introduce students to basic knowledge of Continuum Mechanics and particularly of Solid Mechanics, starting from the basic knowledge of physics up to the definition of stresses and strains in a continuous body, more usual constitutive laws, with particular reference to linear elastic and isotropic behaviour, to the presentation of the strength criteria. The course also introduces the basic elements of the geometry of masses. The course is preparatory to Scienza delle Costruzioni, Idraulica, Meccanica delle Terre

Prerequisites

basic knowledge of Analysis and Physics

Syllabus

Basic concepts of Physics : Vectors and their properties; Tensors and their properties; Equations of Dynamics; Equations of Statics.
