Course objectives
This curriculum is designed for students who already possess knowledge of material properties and their fundamental principles. It focuses on methods for selecting and using various materials for specific applications, life cycle analysis, and an introduction to selected materials modeling approaches. These include machine learning, finite element methods, and computational thermodynamics.
The practical components of the course involve case studies on the use, selection, or failure of materials. Additionally, examples of modeling implementations applied to practical scenarios will be demonstrated. Through these practicals, students will develop the skills to utilize various software tools and implement models for materials analysis and design.

- Machine learning (ML)
Introduction to ML: supervised/unsupervised learning, regression, classification, data mining. Data handling, cleaning and preparation. Selecting and engineering features and models. Hyperparameters, cross-validation, bias, variance. Most common learning algorithms: linear, polynomial, logistic regression; k-Nearest Neighbors; Support Vector Machines; Decision Trees; Ensemble learning; Random Forests. Introduction to neural networks and deep learning.
- Computational Thermodynamics
Introduction to the CALPHAD method. Single and multicomponent thermodynamic equilibrium. Models for the Gibbs energy. Calculation of phase diagrams. Construction of databases after critical evaluation of experimental information as well as first-principles calculated data. Examples of applications.

Course delivery
48 hours of classroom lectures. 32 hours of laboratory sessions.
Attendance to the lectures is optional. Attendance to the laboratory sessions is always compulsory. Each student should be present at least at the 70% of laboratory sessions.
During these laboratory sessions, students will have the opportunity to practically apply the concepts covered in the lectures. They will also utilize various software packages to support their learning and experimentation. Additionally, students will be organized into working teams, with each team comprising 4 to 6 members.
- Oggetto:
Learning assessment methods
Students will be graded according to:
-
An oral examination consisting of open-ended questions that focus on the content covered during the lectures.
-
The creation of a lab report, which each working team will prepare based on their laboratory activities.
The final grade will be determined by the oral examination and the lab report, each contributing according to their respective CFUs.
