The Course will help the students to increase their capabilities in some fundamental tasks of the mechanical designers, such as the following. A) Capability of applying synthesis techniques to problems in mechanical engineering. This skill will make the students able to design innovative products with methods that are complementary to the classical methods based on material resistance and fatigue. B) Being prepared to the most challenging problems in mechanical design, structure dynamics via FEA , by upgrading their knowledge on fundamental issues of Applied Mechanics that are crucial for the design. C) Capability of applying their skills to the newest fields, such as MEMS/NEMS, Automation, Biomedical and Aerospace applications; D) Capability of designing mechanical components of vehicles, such as, automatic and epicyclic gearbox, differential, suspensions, dampers, steering mechanisms and clutches; E) Creativity in products design, acquired during practical sessions of cognitive techniques, lateral thinking and Atlases consulting.
