Procedure and organisation :

Courses: Experiments for the study of mechanical behavior of materials (Machines, specimens, PID) Sensors and measurement (Principles of measurement, signal conditionning and numerization) Experimental plans Field Measurements – Digital Image Correlation (DIC – 2D/3D)) Numerical methods - field identification of properties Techniques for the analysis of the microstructure of materials (microscopy, X-ray diffraction)

 Tutorials: tensile strengthening (elasticity, plasticity), thermomechanical, damage; heat treatments; image correlation; DTA / DSC; additive manufacturing; metallurgical analyzes, optical microscopy / SEM / TEM; electron diffraction.

Pedagogical objectives :

Content:

Solving a problem related with the mechanics of materials usually requires a precise knowledge of the material constitutive behaviour, and more generally of the basics properties of the material. The property that is aimed at being characterized determines the machine, the shape of the sample, the measurements techniques and also the identification algorithms. This course provides an overview of the classical experimental techniques employed in a material testing laboratory. It also aims at providing an insight into the development of advanced experimental methods, in particular full field measurements (especially kinematic), 1D, 2D, 3D et 4D. And finally it aims also at providing essential working methods that are required in the field of testing, such as estimating the uncertainties and the errors of data sets, or data fields, the spatial or temporal resolution etc... Emphasis will be placed on tutorial work, whose completion, analysis of results and writing will be evaluated by the teachers of the course. An exam will assess the culture acquired in the field of experimental techniques by the student during the semester.
