| EXPECTED LEARNING OUTCOMES AND SKILLS TO ACQUIRE. LEARN THE MECHANICAL MODELS AVAILABLE INTO THE LITERATURE FOR MODELING AND SIMULATING THE MECHANICAL RESPONSE OF FIBER REINFORCED POLYMERIC COMPOSITE MATERIALS. KNOWLEDGE AND UNDERSTANDING KNOW THE MECHANICAL PROPERTIES OF POLYMERIC COMPOSITE MATERIALS AS WELL AS THOSE OF THE INDIVIDUAL CONSTITUENTS: RESINS AND FIBERS. KNOW THE MAIN PRODUCTION TECHNIQUES OF A COMPOSITE MATERIAL: FROM HAND-LAY UP TECHNOLOGY TO PULTRUSION, PASSING THROUGH LAMINATION. KNOW HOW TO EVALUATE THE STRENGTH AND STIFFNESS OF THE COMPOSITE MATERIAL THROUGH EXPERIMENTAL TESTS AND / OR MECHANICAL FORMULATIONS. KNOW THE MECHANICS OF A LAMINATE PROFILE AND OF A PULTRUDED PROFILE. KNOW THE MAIN FRACTURE CRITERIA. ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING KNOWING HOW TO EXTEND THE MECHANICAL MODELS OF PLATE AND BEAM, PREVIOUSLY STUDIED FOR AN ISOTROPIC AND HOMOGENEOUS ELASTIC MATERIAL, TO THE CASE OF ORTHOTROPIC MATERIALS. KNOWING HOW TO EVALUATE THE MECHANICAL BEHAVIOR OF STRUCTURES MADE ENTIRELY OF COMPOSITE MATERIALS WITH PARTICULAR REFERENCE TO STABILITY AND BEAM-COLUMN CONNECTIONS. AUTONOMY OF JUDGMENT KNOWING HOW TO CHOOSE THE STRUCTURAL MODEL TO BE ADOPTED FOR THE CASE IN QUESTION. KNOWING HOW TO CRITICALLY EVALUATE THE RESULTS OF STRUCTURAL ANALYZES, CHECKING THEIR CORRECTNESS THROUGH ELEMENTARY MODELS. COMMUNICATION SKILLS KNOWING HOW TO WORK IN A GROUP AND ORALLY PRESENT THE PROBLEMS RELATED TO THE TOPICS STUDIED. ABILITY TO LEARN. KNOWING HOW TO APPLY THE ACQUIRED KNOWLEDGE AND KNOWING HOW TO INDEPENDENTLY LEARN THE NEW EVOLUTIONS OF KNOWLEDGE. |
| Prerequisites | |
|---|---|
| THE SUCCESSFUL ACHIEVEMENT OF THE OBJECTIVES ABOVE REQUIRES A BASIC UNDERSTANDING OF THE MECHANICS OF SOLIDS AND STRUCTURES. |
| Contents | |
|---|---|

| Teaching Methods | |
|---|---|
| THE COURSE PROVIDES THEORETICAL LESSONS (4 CFU) AND PRACTICAL ONES (2 CFU). ATTENDANCE IN PERSON IS STRONGLY RECOMMENDED, ALTHOUGH NOT MANDATORY. |
| Verification of learning | |
|---|---|
| THE ORAL EXAM LASTING ABOUT 60 MINUTES INCLUDES THE DISCUSSION OF THE PROJECT, AIMED AT VERIFYING THE STUDENT'S ABILITY TO INDEPENDENTLY/GROUP DEVELOP A NUMERICAL CODE (IN VISUAL BASIC) RELATING TO THE BEHAVIOR OF LAMINATED COMPOSITE MATERIALS. THE ORAL EXAM WILL VERIFY THE THEORETICAL KNOWLEDGE, WITH PARTICULAR REFERENCE TO MICRO AND MACRO MECHANICS, THE THEORY OF LAMINATION AND PULTRUDED COMPOSITE MATERIALS. THE SCORE OF THE ORAL EXAM DEPENDS ON THE GRADE IN-DEPTH STUDY OF THE PAPER AND THE STUDENT'S ABILITY TO EFFECTIVELY PRESENT THE CONTENTS AND CRITICALLY DISCUSS THE TOPICS ILLUSTRATED. EXCELLENCE REQUIRES THE USE OF AN ADEQUATE SCIENTIFIC LANGUAGE PROPERTY AS WELL AS THE ABILITY TO KNOW HOW TO CORRELATE THE VARIOUS TOPICS OF THE COURSE WITH OTHER DISCIPLINES. |
