Objectives
THE MAIN PURPOSE OF THE COURSE DEALS WITH THE FUNDAMENTALS OF THE MECHANICS OF COMPOSITE MATERIALS, FROM BOTH A THEORETICAL AND EXPERIMENTAL POINT OF VIEW. ENGINEERING ASPECTS RELATED TO SHAPE MEMORY ALLOYS AND PERIODIC MATERIALS ARE ALSO FOCUSED.
Prerequisites
A GOOD KNOWLEDGE OF ADVANCED MATHEMATICS AND MECHANICS IS REQUIRED. THIS CAN BE ACHIEVED IF THE EXAMINATION OF THE COURSE “SCIENZA DELLE COSTRUZIONI II” WAS PASSED. A GOOD UNDERSTANDING OF TECHNICAL ENGLISH IS ALSO REQUIRED.
Contents
A) COMPOSITE MATERIALS FOR CIVIL ENGINEERING.
MANUFACTURING PROCESSES OF COMPOSITE MATERIALS. GEOMETRIC PROPERTIES. VALUES OF STRENGTH AND NORMAL ELASTIC MODULI (BOTH IN TRACTION AND IN COMPRESSION) WITH RESPECT TO THE THREE NATURAL AXES. SHEAR MODULI. POISSON MODULI. CONSTITUTIVE BEAVIOUR (LINEAR-ELASTIC ORTHOTROPIC). DISCUSSION ABOUT SPECIFIC CASES CONCERNING PULTRUDED OR LAMINATED FRP. FAILURE CRITERIA.

B) STRUCTURAL STRENGTHENING.
BASIC DESIGN FOR THE REINFORCEMENT OF PREEXISTING STRUCTURES. PARTIAL FACTORS (MATERIALS, COMPONENTS AND RESISTANCE MODELS). ENVIRONMENTAL CONDITIONS AND CORRESPONDIG PARTIAL FACTORS. PARTIAL FACTORS FOR ACCOUNTING THE EFFECT OF LONG TIME (DEAD) LOADS. STRENGTHENING OF R.C. (NORMAL/PRESTRESSED) STRUCTURES. EVALUATION OF THE RESISTANCE WITH RESPECT TO THE DEBONDING MECHANISM.

C) ADESIVE JOINTS.
INTERFACIAL BEHAVIOUR. BASICS OF COHESIVE FRACTURE MECHANICS. ADESIVE BONDING. FAILURE CRITERIA FOR MODE I, MODE II AND MIXED MODE I/II FRACTURE.

D)FIBER REINFORCED CONCRETE (FRC).
STRUCTURAL USE OF MODIFIED CONCRETE WITH FIBRE ADDITION (METAL OR PLASTIC FIBRES). EXPERIMENTAL CHARACTERIZATION AND PREDICTIVE MODELS FOR THE FINAL COSTITUTIVE BEHAVIOR OF FRC.

E) INNOVATIVE REINFORCING BARS FOR CONCRETE STRUCTURES.
USE OF FRP BARS AND STIRRUPS FOR R.C. MEMBERS.
PARTIAL FACTORS. FLEXURAL AND SHEAR DESIGN FORMULAE.

F) PULTRUDED COMPOSITE BEAMS.
VISCOSITY, SHEAR DEFORMABILITY AND STABILITY OF PULTRUDED COMPOSITE THIN-WALLED PROFILES WITH OPEN CROSS SECTION.

G) SHAPE MEMORY ALLOYS.
NOTES ON SHAPE MEMORY ALLOYS. CONSTITUTIVE BEHAVIOUR. APPLICATIONS IN THE FIELD OF CIVIL ENGINEERING.

H) PERIODIC MATERIALS.
NOTES ON MATERIALS WITH MICROSTRUCTURE. PERIODIC MATERIALS.
Teaching Methods
THE COURSE PROVIDES THEORETICAL AND APPLICATIVE LESSONS. THEORETICAL LESSONS ARE APPROXIMATELY 60% OF TOTAL WHILE THE REMAINING 40% CONCERNS NUMERICAL APPLICATIONS AND LABORATORY ACTIVITIES.
Verification of learning
THE FINAL EXAMINATION IS AN ORAL INTERVIEW IN WHICH THE STUDENT IS CALLED TO DISCUSS TOPICS INCLUDED IN THE PROGRAM, ALSO SUBMITTING AN APPLICATIVE EXAMPLE DEVELOPED DURING THE COURSE.
Texts
SOME TUTORING NOTES ARE PROVIDED TO STUDENTS DURING THE COURSE.
THE FOLLOWING TECHNICAL DOCUMENTS PUBLISHED BY CNR ARE PART OF THE BIBLIOGRAPHIC KIT: DT 200/2012; DT 201/2005; DT 202/2005; DT 203/2006; DT 204/2006; DT 205/2007.
FOR THE ASPECTS RELATED TO THE MATERIALS WITH A PERIODIC STRUCTURE, THE CONSULTATION OF THE FOLLOWING TEXT-BOOK IS SUGGESTED:
GIBSON, L.J.; ASHBY, M.F., CELLULAR SOLIDS: STRUCTURE AND PROPERTIES. CAMBRIDGE UNIVERSITY PRESS, CAMBRIDGE, 1997.
