Objectives
THE MAIN PURPOSE OF THE COURSE DEALS WITH THE FUNDAMENTALS OF THEORETICAL AND EXPERIMENTAL MECHANICS OF COMPOSITE MATERIALS. ARE ALSO COVERED THE ENGINEERING ASPECTS RELATING TO THE SHAPE MEMORY ALLOYS, STRUCTURAL GLASSES AND MATERIALS WITH PERIODIC STRUCTURE.
THE LEARNING OUTCOMES INCLUDE:
- THEORETICAL ASPECTS OF THE MECHANICAL BEHAVIOR OF COMPOSITE MATERIALS AND THEIR FAILURE CRITERIA;
- COHESIVE FORMULATIONS FOR MODELING THE STRUCTURAL ADHESION;
- MAIN ASPECTS OF THE INTERACTION BETWEEN STRUCTURAL ELEMENTS OF DIFFERENT MATERIAL BONDED BY MEANS OF COHESIVE INTERFACES;
- THEORETICAL ASPECTS OF THE BEHAVIOR OF SHAPE MEMORY ALLOYS;
- THEORETICAL ASPECTS OF THE MECHANICAL BEHAVIOR OF STRUCTURAL GLASSES;
- DYNAMIC BEHAVIOR OF PERIODIC MATERIALS IN TWO-DIMENSIONAL DOMAIN.

THE MAIN SKILLS ACQUIRED INCLUDE:
- ABILITY TO CHARACTERIZE EXPERIMENTALLY THE PARAMETERS OF THE CONSTITUTIVE LAWS FOR COMPOSITE MATERIALS;
- ABILITY TO APPLY SIMPLE NUMERICAL MODELS FOR PREDICTING THE STRUCTURAL BEHAVIOR OF AN ADHESIVE JOINT;
- ABILITY TO DESIGN THE REINFORCEMENT / CONFINEMENT OF EXISTING STRUCTURES BY USING COMPOSITE MATERIALS;
- ABILITY TO DESIGN SIMPLE STRUCTURAL SOLUTIONS BY USING STRUCTURAL GLASSES IN A LAYERED CONFIGURATION.
- ABILITY TO ANALYZE THE DYNAMIC RESPONSE OF MATERIALS WITH A 2D PERIODIC MICROSTRUCTURE.
-ABILITY TO SUMMARIZE WITHIN A TECHNICAL REPORT THE CONCEPT, THE APPROACH, THE ANALYSIS AND THE RESULTS OF AN ENGINEERING PROBLEM WITH INNOVATIVE MATERIALS
- ABILITY TO SEARCH FOR BIBLIOGRAFIC NOVEL RESULTS WITHIN THE CONTEXT OF INNOVATIVE STRUCTURAL MATERIALS BY MEANS OF THE MOST COMMON TECHNICAL-SCIENTIFIC DATABASES (I.E. SCOPUS)
