Learning unit 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)
- Calculation of internal forces in a truss
- Security concepts
- Study of the different internal forces in a beam section - how to pass from internal forces (MNT) to stresses (axial and shear stresses)
- Deflections in structures made of beams
- Concept of second order analysis and notions of elastic buckling of beams in compression
Learning outcomes of the learning unit
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 and trusses.
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 elastic buckling the the columns
- Calculate the internal forces in a truss structure
Prerequisite knowledge and skills
Course of « Physique Générale », of « Analyse Mathématique» and of « Algèbre »
Planned learning activities and teaching methods
Organisation:
- Lectures are ex-cathedra courses. They are taught in French but the PowerPoint presentations are in English (2 hours per week). Time for questions is allowed especially after each lesson or during breaks.
- Sessions for exercises (2 hours per week); the latter are solved, explained and commented by student-instructors or teachers. The active participation of students is hightly recommanded during exercises sessions. These exercises sessions are given in French.
- Complementary exercises proposed to the students, for students to train themselves to solving exercises (in the specific exercise book of the course and in the specific booklet for the exercises - final answers are given).
- home-made assignments (compulsory): resolution of exercices representative of what the student should be able to do at the end of the course.
- 3 special sessions for questions and answers (optional). A team of students-instructors together with teachers is in a classroom for 1 hour to answer the questions of the students. The schedule and classes for these sessions are provided via CELCAT.
- A mandatory visit to the laboratory session (compulsory - 1 1/2 hour); some of the taught principles will be illustrated.
Mode of delivery (face to face, distance learning, hybrid learning)

Course materials and recommended or required readings
Platform(s) used for course materials:
- eCampus
Further information:
Theory
- Photocopies of the book " "Mécanique des Matériaux » (S. Cescotto) (available by CdC, "Centrale des Cours")
- The two first chapters of the book for the courses of "Mécanique du Solide" (/!\ the engineers-architects and the civil engineers in the Construction and Mechanics options, need the whole book of "Mécanique du Solide" taught in the second semester) (available by CdC, "Centrale des Cours")
- The slides presented during the courses are made available on eCampus, as far as possible before the theoretical courses
- Book of exercises (available by CdC, "Centrale des Cours")
- The two first chapters of the book for the courses of "Mécanique du Solide" (/!\ the engineers-architects and the civil engineers in the Construction and Mechanics options, need the whole book of "Mécanique du Solide" taught in the second semester) (available by CdC, "Centrale des Cours")
- A specific booklet containing the main theoretical aspects required to solve the exercises; it is made available on eCampus
- A collection of solved exercises, available on eCampus
Exam(s) in session
Any session
- In-person
written exam ( open-ended questions )
Further information:
- Two homeworks (in French)
- Written exam (in French): open questions on theory (1 hour) and solution of problems (3 hours)
- theory : none
- exercises : specific booklet containing the main theoretical aspects required to solve the exercises, calculator...
The homeworks are inseparable from the teaching unit and considered mandatory.
In the two sessions of exam, the following distribution is classically applied:
- 10% for the homeworks
- 35% for the "theory" part of the exam (open questions)
- 55% for the "exercises" part of the exam
It will not be possible to resubmit the homeworks for the second session.

Organisational remarks and main changes to the course
Theoretical courses and sessions of exercises are organised on the Sart-Tilman campus (cf. CELCAT). All informations are communicated through eCampus. To have access, students should have validated their study program.
Main changes made to the course, in particular to account for EVALENS comments:
- For all exercise sessions, typed notes containing the solutions to the presented exercises are made available. During the exercise sessions, students will thus be able to concentrate on understanding the posed problems rather than on copying down the solutions to the exercises.
- Some exercise sessions will be delivered in auditorium by one of the teachers
- For the written exercise exam, students will no longer have access to the solved exercises. They will only be allowed to have the exercise book containing the theoretical reminders useful for solving the exercises.

- The assistants will as much as possible answer the questions sent by email, knowing that it is always better and easier to make an appointment and discuss orally of your questions.
- The assistants will no longer answer questions concerning the course during the last 2 days before an exam or the submission of a report.
