99632 - Principles of Structural Mechanics

Learning outcomes

To provide the elements of solid mechanics useful in determining the stress and strain status of beams subject to the main stress characteristics: axial stress, bending moment, torsion and shear. To provide the basic knowledge of the mechanical properties of materials, experimental methods and quality control procedures. To make the students able to solve hyperstatic structures and perform structural safety assessment.

Course contents

Requirements/Prior knowledge

A prior knowledge and understanding of Mathematics and Physicsis required to attend the course proficiently.

Course Content

1. Course introduction
2. Static and kinematic of the rigid body
3. Static and kinematic of a system of rigid bodies
4. Internal action in a beam like solid
5. Theory of statically determined structures
6. Stress and Strain analysis
   
7. Stress-strain relation in elastic materials

Teaching methods

The course content will be entirely covered by the lectures. The course consists in lectures and on sessions devoted to exercises, which will cover the practical aspects of the lectures. The instructors will supervise students during the laboratory activities.

Assessment methods

Achievements will be assessed by the means of a final written and oral exam, aimed at assessing the "expected learning outcomes" described above.

• The written exam consists of 3 exercises to be solved in 3 hours (30 points).

• The oral exam consists in 3 questions, often to be answered in written form, plus a discussion (30 points).

The written and oral tests are closed book exams. The final grade is the average of the written and oral tests.

To obtain a passing grade (minimum is 18 points) students are required to demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language.

Higher grades (maximum is 30 points, cum laude) will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents.

In case of failure students can take any next final term, generally there are 6 final terms per academic year.

Teaching tools

The teaching tools are tablet, projector and PC.
