A Practical Guide to Reliable Finite Element Modelling

• Gebundenes Buch

Produktbeschreibung

Many books have been written about the finite element method; little however has been written about procedures that assist a practicing engineer in undertaking an analysis in such a way that errors and uncertainties can be controlled. In A Practical Guide to Reliable Finite Element Modelling, Morris addresses this important area. His book begins by introducing the reader to finite element analysis (FEA), covering the fundamental principles of the method, whilst also outlining the potential problems involved. He then establishes consistent methods for carrying out analyses and obtaining accurate and reliable results, concluding with a new method for undertaking error control led analyses.

The book addresses a number of topics that:

Systematically cover an introduction to FEA, how computers build linear-static and linear-dynamic finite element models, the identification of error sources, error control methods and error-control led analyses.

Enable the reader to support the design of complex structures with reliable, repeatable analyses using the finite element method.

Provide a basis for establishing good practice, thereby providing a legal grounding for the structural reliability of a product.

Demonstrate the method with a final case study involving two illustrative problems.

A Practical Guide to Reliable Finite Element Modelling will hold appeal to practising engineers engaged in conducting regular finite element analyses, particularly those new to the field of FE analysis. It will also be a resource for postgraduate students and researchers addressing problems associated with errors in the finite element method.

Autorenporträt

Alan Morris has recently retired from his post at Cranfield University in the UK as Professor of Structural Analysis. His range of expertise covers the development and application of optimal design and analysis systems, with special emphasis on the finite element methods and structural optimisation programs. Previously, he was a Principal Research Officer in the Royal Aircraft Establishment (now QinetiQ) at Farnborough and was head of the Structures and Optimization Sections at the Advanced Concepts Section.

Rezensionen

"The book is highly recommended for all engineering students, researchers and practicing engineers involved in developing/ utilising finite element techniques. I have confidence that even an experienced analyst would benefit from a review of this material!" ( The Aeronautical Journal, March 2010)
