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 is divided into different modules. In addition to the regular class hours, organized in two modules, a lecture cycle and a workshop will be arranged in the week traditionally dedicated to the workshop of the School of Design.
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.
These topics will refer mainly to the text of the course. Slides and other contributions will be published online during the semester.
