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.

Über Autor(innen)

Erasmo Carrera is currently a full professor at theDepartment of Mechanical and Aerospace Engineering at Politecnicodi Torino. He is the founder and leader of the MUL2 group atthe university, which has acquired a significant internationalreputation in the field of multilayered structures subjected tomultifield loadings, see also www.mul2.com. He has introduced theUnified Formulation, or CUF (Carrera Unified Formulation), as atool to establish a new framework in which beam, plate and shelltheories can be developed for metallic and composite multilayeredstructures under mechanical, thermal electrical and magneticloadings. CUF has been applied extensively to both strong and weakforms (FE and meshless solutions). Carrera has been author andco-author of about 500 papers on structural mechanics and aerospaceengineering topics. Most of these works have been published infirst rate international journals, as well as of two recent bookspublished by J Wiley & Sons. Carrera's papers have hadabout 500 citations with h-index=34 (data taken from Scopus).
Maria Cinefra is currently a research assistant at thePolitecnico di Torino. Since 2010, she has worked as a teachingassistant on the "Non-linear analysis of structures", "Structuresfor spatial vehicles" and "Fundamentals of structural mechanics"courses. She is currently collaborating with the Department ofMathematics at Pavia University in order to develop a mixed shellfinite element based on the Carrera Unified Formulation for theanalysis of composite structures. She is currently working in theSTEPS regional project, in collaboration with Thales Alenia Space.M. Cinefra is also working on the extension of the shell finiteelement, based on the CUF, to the analysis of multi-fieldproblems.
Marco Petrolo is a Post-Doc fellow at the Politecnico di Torino(Italy). He works in Professor Carrera's research group on variousresearch topics related to the development of refined structuralmodels of composite structures. His research activity is connectedto the structural analysis of composite lifting surfaces; refinedbeam, plate and shell models; component-wise approaches andaxiomatic/asymptotic analyses. He is author and coauthor of some 50publications, including 2 books and 25 articles that have beenpublished in peer-reviewed journals. Marco has recently beenappointed Adjunct Professor in Fundamentals of Strength ofMaterials (BSc in Mechanical Engineering at the Turin PolytechnicUniversity in Tashkent, Uzbekistan).
Enrico Zappino is a Ph.D student at the Politecnico diTorino (Italy). He has worked in Professor Erasmo Carrera'sresearch group since 2010. His research activities concernstructural analysis using classical and advanced models,multi-field analysis, composite materials and FEM advanced models.He is co-author of many works that have been published ininternational peer-reviewed journals. Enrico was employed as aresearch assistant in Professor Erasmo Carrera's group fromSeptember 2010 to January 2011, where his research, in cooperationwith Tales Alenia Space (TASI), was about the panel flutterphenomena of composite panels in supersonic flows.
