Seat Ingegneria
A.A. 2015/2016
Credits 9
Hours 90
Period 1s
Language ENG

Prerequisites
Knowledge of topics teached in the courses of “Calculus” (Analisi Matematica), “Geometry” (Geometria), “Physics” (Fisica) and “Statics” (Statica).

Learning outcomes
The topics covered in the course are: kinematics and statics of rigid body systems, mechanics of deformable solids and strenght of materials; elasticity of beams, stress and deformation of beams; systems of rods; hyperstatic systems; equilibrium stability.

Program
1. Kinematics of deformable bodies and analysis of strain 2. Statics of deformable bodies and analysis of stress 3. Constitutive relations and energy relationships 4. The elastic problem 5. The De Saint-Venant (D.S.V.) problem 6. Traction 7. Bending moment (flexure), bendings and traction 8. Approximate theory of shear 9. Torsion 10. The Principle of Virtual Works 11. Displacements method for statically indeterminate structures 12. Yield and strength criteria 13. Stability of elastic equilibrium 14. Variational principles 15. Basics of dynamics of structures

Development of the examination
LEARNING EVALUATION METHODS
The learing evaluation will be done in two steps: - a written examination, where the students have to solve exercises related to the topic of the lectures; - an interview (oral examination) which will involve all the topics discussed during the lectures, including exercised aimed at checking the application of the general theory.

LEARNING EVALUATION CRITERIA
To get a positive evalution, the candidate must: - show that he/she understood the topics developed in the lectures; - be able to elaborate the previous concepts in order to solve problems of structural engineering, including the understanding of complex mechanical behaviours; - be able to understand stresses and deformations which develops within a structure; - be able to determine stresses in beams, perform safety checks, to solve simple structures from statics and kinematics points of view.

LEARNING MEASUREMENT CRITERIA
The final evaluation, expressed by a number from 0 to 30 (positive evaluation from 18 to 30), will be a ponderate average of the evalutions obtained in the written an oral examination.

FINAL MARK ALLOCATION CRITERIA
The student must do preliminary the written examination and to get a positive evaluation (>18/30) to be admitted to the oral examination. To get an overall positive evaluation, the student must get a positive evaluation (>18/30) in both written and oral examinations. The maximum score (30/30) is obtained with a deep knowledge of all the topics. The ”summa cum laude” is for students which will show special cleverness during the examination.
