CODE 66289 ACADEMIC YEAR 2024/2025 CREDITS 6 cfu anno 2 YACHT DESIGN 9268 (LM-34) - LA SPEZIA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/02 LANGUAGE English TEACHING LOCATION LA SPEZIA SEMESTER 1° Semester MODULES Questo insegnamento è un modulo di: SHIP STRUCTURES AND PLANTS TEACHING MATERIALS AULAWEB OVERVIEW The course deals with application of the finite element method in ship structural analysis and design. It includes first engineering principles of the method as well as hints for practical applications. AIMS AND CONTENT LEARNING OUTCOMES The course aims at illustrating criteria and methods for limit state checks of ship and marine structures in general with emphasis on pleasure crafts and yachts, carried out according to shipbuilding fundamental principles and to classification societies rules. Typical case studies are solved either applying analytical and finite element methods, presenting loading actions on structures as well as global and local checks generally adopted in design common practice. AIMS AND LEARNING OUTCOMES Students will be able to apply the finite element method for ship structural design and analysis. A well rounded knowledge, ranging from theoretical basis and lasting with application cases is provided. Moreover, the concept of limit state design, implying different scantling checks, is illustrated encompassing not only typical strength checks but also verifications related to service of pleasure crafts and yachts structures. PREREQUISITES Knowledge of main theories of structural mechanics (advanced course) TEACHING METHODS Lectures and guided exercises in IT class. Totally, 60 hours of lectures, almost equally divided. SYLLABUS/CONTENT Introduction: structural mechanics models (beam, shell theory), finite element method. Limit state checks and application of structural models to ship and offshore structures Modern rule checks: IMO Goal Based Standards, rule scantling checks, general principles and idealization of structural components, models selection depending on check types, definition of actions and application to structural models, relevant implications and approximations. Structural modeling: analytical and numerical models, 2D and 3D models (frames, grillages, plates, orthotropic plates, stiffened panels, complex models). Finite element modeling strategies. Local and global models, primary, secondary and tertiary strength, interaction of structural models. Analysis types: static linear, modal analysis. Post-processing, critical analysis and presentation of results.
