Materials and Simple Structures Part 1

This module is a basic module on the physical properties of materials and on techniques for dimensioning mechanically simple components or systems.

The properties of materials are examined using tensile testing, binary diagrams, and microstructure analysis.

Component dimensioning involves choosing the most suitable material and defining the geometry to ensure static and fatigue resistance. The dimensional analysis process also makes it possible to determine the characteristics of a more complex system based on experiments conducted on a scale model.

• Apply the dimensional analysis approach to study a system based on measurements taken on a model.
• Know the main categories of materials and their specific characteristics,
• Determine the mechanical properties of a material based on a tensile test, a basic test for materials engineers.
• Determine the most suitable material for a given application (using Ashby diagrams)
• Dimension a simple part so that it remains within its elastic range (Tresca criterion) and to ensure its fatigue life under asymmetrical loads (Goodman criterion), while taking into account the phenomenon of stress concentration.
