CODE 72322 ACADEMIC YEAR 2016/2017 CREDITS 6 cfu anno 3 INGEGNERIA MECCANICA (L-9) - SCIENTIFIC DISCIPLINARY SECTOR ING-IND/14 LANGUAGE Italiano TEACHING LOCATION SEMESTER 1° Semester MODULES Questo insegnamento è un modulo di: MACHINE DESIGN OVERVIEW The objective of this course is to provide the concepts, procedures, decision analysis techniques necessary to design machine elements commonly found in mechanical devices. AIMS AND CONTENT LEARNING OUTCOMES The course aims to provide students of the knowledge and understanding of the criteria of structural design of the main mechanical members. TEACHING METHODS Classroom lessons SYLLABUS/CONTENT 1st part – Fundamentals of machine design Recalls of statics and kinematics of rigid bodies. Tension and strain in solids. Equilibrium of deformable bodies. Loads diagrams. Area of cross sections. Theory of the beams (subjected to tensile, compression, shear, bending, torsion). Effects superposition. Equation of the elastic line. Conventional structural materials (mechanical properties). 2nd part – Criteria of structural design Static strength of materials. Ideal or equivalent stress. Strength criteria for ductile materials. Strength criteria for brittle materials. Safety condition: Limit stress, Safety factor, Admissible stress. Notches and their effect. Elastic and experimental stress concentration factor. Safety condition in presence of notches. Fatigue in metallic materials. Fatigue spectra. High cycle fatigue: Wöhler curves; Influence of the mean stress; Notches and their influence; Size factor; Surface factor. Safety condition for stresses of constant amplitude. Safety condition for stresses of variable amplitude: Cumulative damage. Long columns with central loading. Euler column formula.
