Objectives
EXPECTED LEARNING OUTCOMES AND SKILLS TO BE ACQUIRED.
LEARN THE COMPUTATIONAL METHODS PRESENT IN THE LITERATURE FOR MODELING AND SIMULATING THE MECHANICAL RESPONSE OF 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.

Teaching Methods
THE COURSE PROVIDES BOTH THEOERITICAL AND PRACTICAL LECTURES.
Verification of learning
THE ACHIEVEMENT OF THE OBJECTIVES IS ASSESSED BY MEANS OF AN ORAL EXAM. ON THIS OCCASION THE STUDENTS ARE REQUESTED TO SOLVE EXERCISES ON PROBLEMS RELATED TO THEORETICAL TOPICS DEVELOPED IN THE COURSE. FOR THE PURPOSES OF FINAL JUDGMENT THE QUALITY OF THE EXPOSITION WILL BE TAKEN INTO ACCOUNT, IN TERMS OF THE USE OF APPROPRIATE SCIENTIFIC LANGUAGE, THE ABILITY TO CROSS-CORRELATION BETWEEN THE DIFFERENT TOPICS OF THE COURSE AND, WHERE POSSIBLE, WITH OTHER DISCIPLINES.
