The course aims to provide students with the knowledge needed for the analysis and the structural design of mechanical components made of advanced materials and composites.
The course focuses on the design with advanced materials (i.e fiber-reinforced composites, laminates, sandwich structures) considering mechanical behavior and constitutive models, analytical and numerical methods and resistance criteria, joining techniques.
Definition and classification of composite materials

Unidirectional lamina: micromechanics, macromechanics, theoretical models and experimental characterization, failure modes, failure criteria
Laminates: Classical lamination theory (CLPT), classification of laminate types, effective elastic constants, interlaminar stresses.
Design of composite laminates: analytical and numerical methods, example applications, flexure of laminate beams.
