Finite Element Analysis originated from the need for solving complex elasticity and structural analysis problems in civil and aeronautical engineering, and its development can be traced back to 1941. It consists of a numerical technique for finding approximate solutions to partial differential equations as well as integral equations, permitting the numerical analysis of complex structures based on their

This book represents a selection of chapters exhibiting various investigation directions in the field of Finite Element Analysis. It is composed of 20 different chapters, and they have been grouped in three main sections: "*Dentistry, Dental Implantology and Teeth Restoration*" (6 chapters), "*Cardiovascular and Skeletal Systems*" (4 chapters), and "*Materials, Structures, Manufacturing Industry and Industrial Developments*" (10 chapters).

The chapters have been written individually by different authors, and each chapter can be read independently from others. This approach allows the selection of a chapter the reader is most interested in, without being forced to read the book in its entirety. It offers a colourful mix of applications of Finite Element Modelling ranging from orthodontics or dental implants, to percutaneous heart valve devices, intervertebral discs, thermal conductivity, elastic waveguides, and several other exciting topics.

This book serves as a good starting point for anyone interested in the application of Finite Elements. It has been written at a level suitable for use in a graduate course on applications of finite element modelling and analysis (mechanical, civil and biomedical engineering studies, for instance), without excluding its use by researchers or
