The Elastic Analysis Of Flat Grillages

First published in 1965, this book was written in response to the considerable changes that had taken place in shipbuilding techniques since 1945 and to the new scientific methods that were being increasingly adopted in a strongly competitive market. It describes the advances which had been made in one field of the design of ship structures, a field also of importance in the design of bridges and other rigid structures on land. A grillage is a structure of intersecting beams, usually attached to one side of a continuous plate panel, which is loaded normal to its surface. The decks, bottoms and bulkheads (vertical divisions) of ships are usually flat grillages, and this form of construction is also commonly used in the decks of bridges. The methods of plastic analysis are not directly applicable to plated grillage structures and Mr Clarkson has therefore discussed only elastic methods of design.

Ship structures can be extremely large, and their structural arrangements are often complex and of a considerable variety. Local Strength of Ship Structures examines the basic aspects of ship structural analysis and design using mathematical tools, with an emphasis on an understanding of the physics of the behaviour of these structures. A fundamental understanding of these concepts is essential to use computer‐based tools effectively. In addition to mathematical models, reference is made to test data that have been obtained over many years and used to gain insight into ship structural behaviour. Features: Provides an introduction to local ship strength problems, structural arrangements and the different types of materials used in ship construction Examines the fundamentals of engineering mechanics with a particular focus on marine structure problems Covers the basics of ship structural analysis and design using mathematical tools

This book presents selected papers from the 2nd Workshop on “Durability of Composites in a Marine Environment”, which was held in Brest, France in August 2016. Providing an overview of the state of the art in predicting the long-term durability of composite marine structures, it addresses modelling water diffusion; damage induced by water accelerated testing, including durability in design; in-service experiences; ocean energy; and offshore applications. Ensuring long-term durability is not only necessary for safety reasons, but also determines the economic viability of future marine structures, and as such, the book is essential reading for all those involved with composites in the marine industry, from initial design and calculation through to manufacture and service exploitation. It also provides information unavailable elsewhere on the mechanisms involved in degradation and how to take account of them.

The engineering design of structures and machines consists often in finding the best solution among a finite number of feasible decisions. This volume comprises problems and solution methods for discrete structural optimization. Exact, approximate and heuristic methods are presented applying deterministic and stochastic approaches.
