Introduction to Finite Elements in Engineering by Tirupathi R. Chandrupatla

Introduction to Finite Elements in Engineering by Tirupathi R. Chandrupatla


The first edition of this book appeared over 10 years ago and the second edition followed a few years later. We received positive feedback from professors who taught from the book and from students and practicing engineers who used the book. We also benefited from the feedback received from the students in our courses for the past 20 years. We have incorporated several suggestions in this edition. The underlying philosophy of the book is to provide a clear presentation of theory, modeling, and implementation into computer programs. The pedagogy of earlier editions has been retained in this edition.
New material has been introduced in several chapters. Worked examples and exercise problems have been added to supplement the learning process. Exercise problems stress both fundamental understanding and practical considerations. Theory and computer programs have been added to cover acoustics, axisymmetric quadrilateral elements, conjugate gradient approach, and eigenvalue evaluation. Three additional programs have now been introduced in this edition. All the programs have been developed to work in the Windows environment. The programs have a common structure that should enable the users to follow the development easily. The programs have been provided in Visual Basic, Microsoft Excel/Visual Basic, MATLAB, together with those provided earlier in QBASIC, FORTRAN and C. The Solutions Manual has also been updated.

The Finite Element Method in Engineering by Singiresu S. RAO

The Finite Element Method in Engineering by Singiresu S. RAO 

Finite Element Analysis is an analytical engineering tool originated by the Aerospace and nuclear power industries to find usable, approximate solutions to problems with many complex variables. It is an extension of derivative and integral calculus, and uses very large matrix arrays and mesh diagrams to calculate stress points, movement of loads and forces, and other basic physical behaviors. Rao provides a thorough grounding of the mathematical principles for setting up finite element solutions in civil, mechanical, and aerospace engineering applications. The new edition includes examples using modern computer tools such as Matlab, Ansys, Nastran, and Abaqus. 

Professional engineers will benefit from the introduction to the many useful applications of finite element analysis, and will gain a better understanding of its limitations and special uses. 
New to this edition: Examples and applications in Matlab, Ansys, and Abaqus Structured problem solving approach in all worked examples New discussions throughout, including the direct method of deriving finite element equations, use of strong and weak form formulations, complete treatment of dynamic analysis, and detailed analysis of heat transfer problems
More examples and exercises All figures revised and redrawn for clarity


                                                                  


Rocket and Spacecraft Propulsion: Principles by Martin J. L. Turner


Rocket and Spacecraft Propulsion: Principles by Martin J. L. Turner


"Turner (Univ. of Leicester, UK) offers an updated version of his 2000 book. … He examines rockets and rocket engines from the viewpoint of physical principles and gives accessible explanations on how rockets work. … Turner uses graphs to help interpret many equations. … Summing Up: Recommended. Upper-division undergraduates; graduate students." (D.B. Mason, CHOICE, Vol. 42 (10), June, 2005)
"As a rule, textbooks have equations and other books have colour photographs, but this book breaks that rule by including both. Its centre-section of 20 colour plates certainly sets it apart from most textbooks … . there is plenty of information between the equations to engage anyone with an interest in the technology. It also has a number of appendices and a five-page index. … The book is usefully up to date in its coverage. … This book remains an excellent primer on the principles of rocket propulsion." (Mark Williamson, International Space Review, 2005)
The revised edition of this practical, hands-on book discusses the launch vehicles in use today throughout the world, and includes the latest details on advanced systems being developed, such as electric and nuclear propulsion.
The author covers the fundamentals, from the basic principles of rocket propulsion and vehicle dynamics through the theory and practice of liquid and solid propellant motors, to new and future developments.
He provides a serious exposition of the principles and practice of rocket propulsion, from the point of view of the user who is not an engineering specialist. 



Aircraft Conceptual Design Synthesis by denis howe

Aircraft Conceptual Design Synthesis by denis howe



Aircraft Conceptual Design Synthesis means design by fitness-for-purpose. Design engineers can jump off from the point of given parameters and requirements – required performance, payloads and other factors.
This is the first book for the aeronautical designer devoted to guiding the reader through this highly effective conceptual design synthesis process. This forms the procedure for the initial stage of the aircraft design process – the interpretation of a requirement into the preliminary layout. A logical design sequence is developed utilizing original modules to represent propulsion, lift, drag, mass, and performance. Aircraft Conceptual Design Synthesis includes a disk of spreadsheets that provides core data. Unlike existing approaches, the design synthesis method can be applied to novel aircraft concepts.
CONTENTS INCLUDE
  • The design process
  • Aircraft configuration
  • Flight regime and powerplant considerations
  • Fuselage layout
  • Configuration of the wing
  • Basic lift, drag and mass representations
  • Performance estimation
  • Parametric analysis and optimisation
  • Analysis of concept design
