The course aims to address the issues related to materials choice for optimal design, providing the tools for correct material and technology selection for specific applications.
The course, organized in different modules, is intended to provide the tools to perform the best material selection for products design.
In detail, the main topics addressed in the modules are the following:
- Introduction to the materials selection process;
- Materials and processes classification: tree structures;
- The strategic approach: how to select the best materials for the project;
- Weight and stiffness of the component: material density and elastic modulus;
- Flexion, bending and vibration: how materials stiffness can affect the project;
- Materials elasticity, plasticity, yield strength and ductility;
- Bending and break: how materials resistance can affect the project;
- Fracture and fracture toughness;
- Cyclic loads, fatigue damage and breakage;
- Breakage of a component: how materials fracture can affect the project;
- Rubbing, slipping and galling: friction and wear;
- Atoms in vibration: heat;
- Materials for high temperature applications;
- Conductors, insulators and dielectrics;
- Magnetic materials;
- Materials for optical devices;
- Durability: oxidation, corrosion and degradation;
- Heat treating, deforming, joining and finishing: the processes;
- Follow the recipe: processes and materials properties;
- Materials, processes and environment.
Many example of materials and process selection will be organized and proposed in classroom.
Many selection cases will consider the use of a software tool, CES (Cambridge Engineering Selector).
Slides and other contributions will be published online before each coresponding lesson.
