Principles of Naval Architecture-Intact Stability(اصول معماری کشتی- پایداری)

درک پایداری و ایستایی کشتی – توانایی یک کشتی برای بازگشت به حالت اولیه بعد از اختلال در نیروها و زمان‌ها – برای تمام دانشجویان دریایی و متخصصانی که برای یک زمینه خاص و یا کسب گواهینامه مهندسی، درس می‌خوانند و یا به‌دنبال ارتقا به رتبه‌های بالاتر در شرکت‌ها و موسسات دریایی می‌باشند؛ حیاتی است. 

این کتاب  110 صفحه ای  از مجموعه ارزشمند اصول معماری کشتی است.

Preface
During the twenty years that have elapsed since publication of the previous edition of this book, there have been remarkable advances in the art, science and practice of the design and construction of ships and other floating structures. In that edition, the increasing use of high speed computers was recognized and computational methods were incorporated or acknowledged in the individual chapters rather than being presented in a separate chapter Today, the electronic computer is one of the most important tools in any engineering environment and the laptop computer has taken the place of the ubiquitous slide rule of an earlier generation of engineers
Advanced concepts and methods that were only being developed or introduced then are a part of common engineering practice today. These include finite element analysis, computational fluid dynamics, random process methods, numerical modeling of the hull form and components, with some or all of these merged into integrated design and manufacturing systems. Collectively, these give the naval architect unprecedented power and flexibility to explore innovation in concept and design of marine systems. In order to fully utilize these tools, the modern naval architect must possess a sound knowledge of mathematics and the other fundamental sciences that form a basic part of a modern engineering education In 1997, planning for the new edition of Principles of Naval Architecture was initiated by the SNAME publications manager who convened a meeting of a number of interested individuals including the editors of PNA and the new edition of Ship Design and Construction on which work had already begun. At this meeting it was agreed that PNA would present the basis for the modern practice of naval architecture and the focus would be principles in preference to applications. The book should contain appropriate reference material but it was not a handbook with extensive numerical tables and graphs
