| Objectives | |
|---|---|
| KNOWLEDGE AND UNDERSTANDING: FUNDAMENTAL PRINCIPLES OF OPERATING, KINEMATIC AND DESIGN OF SIMPLE MECHANICAL OR STRUCTURAL ELEMENTS; MATERIALS BEHAVIOR, STARTING FROM THE DEFINITIONS OF STRESS, STRAIN AND THEIR RELATIONSHIP; EQUILIBRIUM EQUATIONS OF ELASTICITY; BEAM THEORY AND ASSESSMENT OF INTERNAL FORCES AND DEFORMATIONS; MODELLING THE MECHANICAL STRUCTURE AS A BEAM OR AS A COMBINATION OF INTERCONNECTED BEAMS; DESIGN AND VERIFICATION PROCEDURE OF SIMPLE ELEMENTS OR GROUPS THAT MAY BE RELATED TO EQUIPMENT OR MECHANICAL ELEMENTS SUBJECTED TO DIFFERENT FORCES AND CONSTRAINTS, DEPENDING ON GEOMETRY, BOUNDARY CONDITIONS AND MATERIALS. APPLYING KNOWLEDGE AND UNDERSTANDING ENGINEERING ANALYSIS THE STUDENT WILL BE ABLE TO DEAL WITH THE ANALYSES OF THE KINEMATIC BEHAVIOR AND STRENGTH PREDICTION OF SIMPLE MECHANICAL ELEMENTS; MOREOVER, ABLE TO IDENTIFY THE MOST APPROPRIATE METHOD FOR PERFORMING A STRESS-STRAIN ANALYSIS IN ORDER TO DESIGN SIMPLE MECHANICAL COMPONENTS, OPTIMIZING THE CALCULATION PROCESS BASED ON THE STARTING DATA AND THE BOUNDARY CONDITIONS. APPLYING KNOWLEDGE AND UNDERSTANDING ENGINEERING DESIGN DESIGN AND VERIFICATION OF SIMPLE ELEMENTS OR SYSTEMS RELATED TO EQUIPMENT OR MECHANICAL ASSEMBLIES SUBJECTED TO DIFFERENT FORCES AND CONSTRAINTS, DEPENDING ON GEOMETRY, BOUNDARY CONDITIONS AND MATERIAL LAW. MAKING JUDGMENTS - ENGINEERING PRACTICE: BY THE END OF THE COURSE, THE STUDENT WILL BE ABLE TO APPLY THE PROPER CALCULATION SCHEMES TO A GIVEN MECHANICAL PROBLEM. ABILITY TO EVALUATE THE STATIC BEHAVIOR OF A SIMPLE STRUCTURE. COMMUNICATION SKILLS TRANSVERSAL SKILLS: UNDERSTANDING THE NOMENCLATURE AND DEFINITIONS RELATING TO THE FIELDS OF STRENGTH OF MATERIALS AND MECHANICS OF DEFORMABLE BODIES; ABILITY TO EXPLAIN THE CHOSEN CALCULATION APPROACH. LEARNING SKILLS TRANSVERSAL SKILLS APPLICATION OF THE ACQUIRED KNOWLEDGE IN CONTEXTS DIFFERENT FROM THOSE PRESENTED DURING THE COURSE. INVESTIGATION SKILLS TRANSVERSAL SKILLS ABILITY IN DEVELOPING SIMPLIFIED SCHEMES TO SOLVE COMPLEX PROBLEMS AUTONOMOUSLY. |

| ACHIEVEMENT OF THE PREFIXED AIMS IS EVALUATED BY MEANS OF A WRITTEN AND AN ORAL EXAMINATION (OPTIONAL). WRITTEN EXAMINATION: CRITERIUM FOR MINIMUM THRESHOLD THE STUDENT HAS TO PROVE THAT KNOWS HOW TO SCHEMATISE A STRUTCTURE, DETERMINING REACTIONS AND STRESS RESULTANT DIAGRAMS. CRITERIUM FOR EXCELLENCE: THE STUDENT DEMONSTRATES A STRONG COMPETENCE IN DIMENSIONING OF A SIMPLE STRUCTURE HIGHLIGTHING GOOD KNOWLEDGE OF THE EMPLOYED FORMULAE. ORAL EXAMINATION: CRITERIUM FOR MINIMUM THRESHOLD THE STUDENT HAS TO PROVE A GOOD KNOWLEDGE OF THE FORMULATIONS CONNECTED TO THE STRESS RESULTANTS, REPRESENTING THEM FOR PLANAR BEAM STRUCTURES, KNOWING THE APPLICATION OF A STRNGTH CRITERIUM TO A GENERAL STRESS TENSOR, KNOWING HOOKE'S LAW. CRITERIUM OF EXELLENCE: IN ADDITION TO THE ABOVE, THE STUDENT HAS TO SHOW THE THEORETICAL DEVELOPMENT OF THE FORMULAS RELATED TO THE STRESS RESULTANTS, DETERMINING PRINCIPAL STRESSES AND MAXIMUM TANGENTIAL STRESSSES, USING DIFFERNT STRENGTH CITERIA, EVALUATING MEMBRANAL STRESSES FOR PRESSURE VESSELS. THE WRITTEN EXAMINATION CAN BE A SUBJECT TO DISCUSS DURING THE ORAL EXAMINATION. THE FINAL GRADE, EXPRESSED IN THIRTIETHS WITH POSSIBLE PRAISE, WILL DEPEND ON THE OVERALL MATURITY ACQUIRED ON THE CONTENTS OF THE COURSE. |
