Simple Materials and Structures, Part 1

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

Material properties are examined through tensile testing, binary diagrams, and microstructure.

Component design involves selecting the most suitable material and defining the geometry to ensure structural integrity and fatigue resistance. The dimensional analysis approach 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 method to study a system based on measurements taken on a model,
• Understand the major categories of materials and their specific characteristics,
• Determine the mechanical properties of a material based on a tensile test, a fundamental test for materials engineers,
• Determine the most suitable material for a given application (using Ashby diagrams)
• Design a simple part so that it remains within its elastic range (Tresca criterion) and to ensure its fatigue life under asymmetric loads (Goodmann criterion), while taking into account the phenomenon of stress concentration.
