## SOLID MECHANICS

CODE 84535 2017/2018 5 credits during the 1st year of 9263 CIVIL AND ENVIRONMENTAL ENGINEERING (LM-23) GENOVA ICAR/08 Italian GENOVA (CIVIL AND ENVIRONMENTAL ENGINEERING ) 1° Semester This unit is a module of: AULAWEB

## OVERVIEW

The course aim is to introduce the mechanics of solids by the formulation of the field equations for the linear elastic boundary value problem. A collection of solutions is presented in detail referring to plane problems and bidimensional theories for plates and shells. Moreover, the course provides the basic knowledge of the finite elements method useful to determine numerical approximate solutions. Some problems of practical interest are also formulated and solved.

## AIMS AND CONTENT

### LEARNING OUTCOMES

The course provides the theoretical development of the mechanics of solids and structures with sufﬁcient rigor to give students a good foundation for the determination of solutions to a broad class of problems of engineering interest. The primary goal is to formulate models, develope solutions and understand the results.

### TEACHING METHODS

The course consists of theoretical lectures and discussion of case studies.

Detailed lecture notes are available on aulaweb.
