Detailed description of topics:

Further to the course mt 822 failure modes and ultimate strength of the structure are considered. Fatigue, crack propagation and brittle fracture play an important role. These aspects are dealt with both in a fundamental way as using practical standard design procedures. The implications of these aspects for the structural design of ships and their details are taught. The structural design can be made in a deterministic as well as probabilistic way. Attention is given to measurements at sea and hull monitoring. Characteristics of the main structural material for ships, i.e. steel, are described and the methods to influence them. Fabrication methods (in particular welding) have a major impact on material properties and consequently the safety of the structure.

Remarks (specific information about assesment, entry requirements, etc.):

A separate student training in the Ship Structures Laboratory accompanies the course.

Goals:

The course is designed to provide all future naval architects with sufficient insight in the design and behaviour of ship and offshore structures, to teach them to make an optimal conceptual design, to teach them the impact of material properties, fabrication and other limiting factors. The students will learn the more important structural analysis methods.

Computer use:

No computers are used in the course.

Laboratory project(s):

In the laboratory project the students learn to determine fatigue and fracture behaviour of the materials.

Design content:

The course is designed to teach structural design, to make response analyses and to assess the acceptability of the responses.

Percentage of design: 50%
