Course contents :
|
| Overview and structure of the course
- Genaral equilibrium principles (identification of all external efforts acting on the studied body, concept of the cut and identification of the internal forces acting on both sides of the cut)
- Notions of stresses and of plasticity surfaces (Mohr circle in in-plane stress field)
- Material properties: link between the stresses and the deformations
- Beam definition
- Calculation of internal forces in a structure constituted of beams (MNT diagrams)
- Security concepts
- Study of the different internal forces in a beam section - how to pass from forces to stresses (tension, compression, bending, torsion, shear, combined loading)
- Deflections in structures made of beams
- Concept of second order analysis and notions of elastic buckling of beams in compression

Learning outcomes of the course :
|
| This course establishes a link between general courses of mathematics, physics and a particular field of the engineering: the mechanics of materials. It strides towards a double objective:
- to teach the students how to make use of notions studied in these general courses in broaching a new subject, implying to "mix" these notions and to develop the aptitude of synthesis and application;
- to give to the students the basics in Material Mechanics and to teach them how to apply these ones to some practical cases of beams.
For engineering students who shall specialize in civil engineering, architecture, mechanics, applied physics, this course will be of basic use for series of more specialized courses, such as mechanics of solids, theory of structures, knowledge of materials, ... It will enable them to integrate the notions of equilibrium and stress on the actual and unidimensional case of beams before studying applications requiring the use of full tensors in the course of Solid Mechanics.
For the others, this course is an education to scientific approach for engineers, while providing basic terminology that will be useful for discussions with specialists.
After the courses, the student should be able, for structures made of beams and for a given loading situation, to achieve the following tasks:
- Draw the MNT diagrams in the structure
- Achieve adequate cuts in the structure and evaluate the corresponding internal forces
- From these internal forces, to calculate the stresses in the cross-section
- Define whether or not the constitutive material may resist to the stresses
- Define how this structure deforms
- Define whether there is a risk of flexural buckling the the columns

Prerequisites and co-requisites/ Recommended optional programme components :
|
| Course of « Physique Générale », of « Analyse Mathématique» and of « Algèbre » |
|
Planned learning activities and teaching methods :
|
|
- Lectures are ex-cathedra courses. They are taught in French (2 hours per week). Time for questions is allowed especially after each lesson or during breaks.
- Session for exercises (2 hours per week); the latter are solved by assistants. The active participation of students is required during exercises sessions. These exercises sessions are given in French.
- Complementary exercises proposed to the students (in a specific exercise book)
- A report (compulsory) on a home-made exercise.
- Three special sessions for questions and answers.
- A visit to the laboratory session (compulsory - 1 1/2 hour); some of the taught principles will be illustrated.
|
|
