LEARNING OUTCOMES

The students attending this course gain the basic knowledge of the structure, architecture and mechanical properties of the Composite Materials, understanding of the mechanical behavior of  metals and composite materials under pseudo static and fatigue loading conditions, prediction of fatigue damage and its correlation with mechanical properties, understanding of the creep and corrosion phenomenon.

This knowledge is necessary and is used in many subsequent courses of Mechanical Engineering and Aeronautics, such as Light Structures, Introduction to Composite Materials, Mechanical Behavior of Materials, Finite Elements for Structural Analysis, Mechanics of Composite Materials etc.

The learning outcomes of this course correspond to the descriptive indicator 8, according to the European Qualifications Framework.
