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.

EXAMS

EXAM DESCRIPTION

The exam is composed of a practical exercise and an oral part. The duration of the practical exercise is 1 hour, and during lectures, similar practical exam trials will be provided.

The oral exam consists of some questions to ascertain comprehension of the theoretical content covered in the course. Additionally, a short technical report about the exercises done during the course is required

ASSESSMENT METHODS

The assignment of the exam grade will take into account:
1) knowledge and understanding of the covered topics;
2) ability and clarity of exposition;
3 ability to solve problems related to the covered topics;
