# Engineering Analysis with ANSYS Software

For all engineers and students coming to finite element analysis or to ANSYS software for the first time, this powerful hands-on guide develops a detailed and confident understanding of using ANSYS's powerful engineering analysis tools. The best way to learn complex systems is by means of hands-on experience. With an innovative and clear tutorial based approach, this powerful book provides readers with a comprehensive introduction to all of the fundamental areas of engineering analysis they are likely to require either as part of their studies or in getting up to speed fast with the use of ANSYS software in working life. Opening with an introduction to the principles of the finite element method, the book then presents an overview of ANSYS technologies before moving on to cover key applications areas in detail.Key topics covered:Introduction to the finite element methodGetting started with ANSYS softwarestress analysis dynamics of machines fluid dynamics problemsthermo mechanics contact and surface mechanicsexercises, tutorials, worked examples With its detailed step-by-step explanations, extensive worked examples and sample problems, this book will develop the reader's understanding of FEA and their ability to use ANSYS's software tools to solve their own particular analysis problems, not just the ones set in the book.

Audience
Professional mechanical, civil and electrical engineers who are developing ANSYS skills; Students of mechanical, civil and electrical engineering taking an introductory Finite Element, modelling and analysis or related course using ANSYS, plus applied areas such as aerospace
