Strength of Materials

General Data
Academic program	General Engineering Program			:
Type d'EC	Classes (LIIAem05ERDM)
Lectures : 22h00 Lab Work : 8h00 Total duration : 40h00	Status :	Period : SEMESTER 5	Education language : French

Learning Outcomes
- calculate the reactions of the connections in the case of an isostatic structure - calculate forces and moments in cross sections of an isostatic beam - calculate normal and shear stresses using calculation formulas or software - measure normal and shear stresses using strain gauges

Content
The presentation of the methods of calculation used in Resistance of the Materials is made in the form of lectures and exercises, concerning the following points: - writing of equilibrium equations and calculation of bond reactions in the case of isostatic structures, - plots of the load diagrams along the average fiber of a beam, - Application of stress calculation formulas in the case of stressed beams in tension / compression, bending, shearing and torsion. This presentation is supplemented by a course on strain gauge strain measurement, which is applied during a lab session. There are two practical works : - Gauge measurements: normal and tangential stress measurements, special gauge assemblies, - dimensioning: use of the resistance of materials to pre-dimension a structure, verification of design using finite element calculation software.
