Course objectives:
|
The course deals with the mechanical properties of composite materials and the behaviour of composite components. Laminated plates with consideration of transverse shear stiffness, sandwich plates, rods and beams are analysed. Attention is paid to the use of finite element method for calculations of composite parts and structures. Changes in the mechanical properties of composite materials due to cyclic loading are shown. Particular attention is paid to adaptive laminates with piezoelectric sensors and actuators, and to laminate structure monitoring.
