A6. To develop the working knowledge and skills to undertake finite element analysis for marine structures
Outline Of Syllabus
This module covers the following topics: grillages, plate behaviour under lateral pressure or in-plate compression, structural dynamics. Frames and grillages are introduced to develop knowledge and skills to analyse elastic and plastic responses of stiffened plate structures. The coverage of elastic plate theory and elasto-plastic plate theory enable the students to deal with plate under lateral pressure. Initial buckling and post buckling of plates and tripping of stiffeners are included for design of plate structure subjected to in-plane compression. Flexural vibration of plates and beams are treated for design of ship structures to avoid vibration..
Elastic responses of grillages; plastic theory and its application to beams and grillages. Elastic plate theory; plate behaviour under lateral pressure.
Elasto-Plastic bending of plate; elastic membrane theory; plate of rupture.
Elastic buckling behaviour of plates; effective width and long plate strength; wide plate strength; interaction equation.
Introduction to structural dynamics; flexural vibration of beams; flexural vibration of plates; design considerations and criteria for limiting vibrations.
Fundamental of both linear and non-linear structural response analysis; ship frame analysis and grillage analysis; structural finite element analysis; formualtions of beam elements, plane stress elements and higher order isoparametric elements; dispalement and shape functions; equivalent nodal loads; beam-bracket compatibility and stiffener-plate compatibility; sub-structure technique; condensation technique structural vibrations

Teaching Rationale And Relationship
- Lectures are designed to convey the underlying concepts and knowledge of marine structural design and analysis (IKO1-IKO22) and the professional skills required to solve structural problems (ISO1-ISO24).
- Tutorials support the students' self study in reading around the lecture material and learning to solve marine structural problems posed by the tutorial questions (ISO1-ISO24).
- Independent study gives time for the students to read recommended references (IKO1-IKO22) and practise their professional skills (ISO1-ISO24).
Should the public health situation require it, the present-in-person teaching activities will be replaced by synchronous online sessions
Students should consult their timetable for up-to-date delivery information.
Assessment Methods
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The timed assessment will assess the breadth of knowledge, understanding and ability to perform related ship strength calculations. This medium also allows students to demonstrate intended learning outcomes across a wide range of topics from the syllabus.
The coursework provides students with the opportunity to demonstrate written communication, teamwork, planning, organisation, initiative, problem solving and acquisition of learned skills.
