Beschreibung
The finite element method (FEM) is a computational tool widelyused to design and analyse complex structures. Currently,there are a number of different approaches to analysis using theFEM that vary according to the type of structure being analysed:beams and plates may use 1D or 2D approaches, shells and solids 2Dor 3D approaches, and methods that work for one structure aretypically not optimized to work for another.
Finite Element Analysis of Structures Through UnifiedFormulation deals with the FEM used for the analysis of themechanics of structures in the case of linear elasticity. Thenovelty of this book is that the finite elements (FEs) areformulated on the basis of a class of theories of structures knownas the Carrera Unified Formulation (CUF). It formulates 1D, 2D and3D FEs on the basis of the same 'fundamental nucleus' that comesfrom geometrical relations and Hooke's law, and presents both 1Dand 2D refined FEs that only have displacement variables as in 3Delements. It also covers 1D and 2D FEs that make use of 'real'physical surfaces rather than 'artificial' mathematicalsurfaces which are difficult to interface in CAD/CAE software.
Key features:
* Covers how the refined formulation can be easily andconveniently used to analyse laminated structures, such as sandwichand composite structures, and to deal with multifield problems
* Shows the performance of different FE models through the 'besttheory diagram' which allows different models to be compared interms of accuracy and computational cost
* Introduces an axiomatic/asymptotic approach that reduces thecomputational cost of the structural analysis without affecting theaccuracy
* Introduces an innovative 'component-wise' approach to deal withcomplex structures
* Accompanied by a website hosting the dedicated software packageMUL2 (www.mul2.com)
Finite Element Analysis of Structures Through UnifiedFormulation is a valuable reference for researchers andpractitioners, and is also a useful source of information forgraduate students in civil, mechanical and aerospaceengineering.
