The subject aims to introduce the student to the design of mechanical and automotive structure with the particular target of lightweight. Lightweight targets can be pursued by using recently developed steels of the families of HSS and UHSS, by using light weight metallic alloys such as Aluminum or by using Fiber Reinforced Plastic such as Composite materials. Some times multi-material structures are considered, taking advantage from the particular properties and manufacturing technologies adopted to make mechanical components. The subject will in particular concentrate on the design with composite materials. Further some basic on the joining technique for multi-material structure will be introduced, with particular attention to adhesive joining. It is expected to develop some experimental lab activities. It is expected to have application testimonials from relevant industries.

Class hours will be equally subdivided in lectures and tutorials. During tutorials It is expected to develop some experimental lab activities. Results of the class exercises and of the Lab test are to be collected by each student in reports to be presented and discussed during the final exam.

In case of remote teaching, Lab activities will be proposed through online connection with the help of movies. Results of the class exercises and of the Lab test are to be collected by each student in reports to be presented and discussed during the final exam.

Modalità di esame: Prova orale obbligatoria; Elaborato scritto individuale;
Exam: Compulsory oral exam; Individual essay;
The final exam is finalized to assess the knowledge gained by each of the students on the subjects developed during lectures and tutorials. Final exam will consist in an oral exam dealing with the subjects developed during lectures and tutorials. Results of the class exercises and of the Lab test, collected by each student in reports, will be discussed and evaluated during the final exam in order to get a comprehensive assessment with respect to the said course targets.
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
