Computational Geometry of Surfaces and Its Application to the Finite Element Analysis of Shells Hardcover – April 10, 2013

"Rebound" by Kwame Alexander
Don't miss best-selling author Kwame Alexander's "Rebound," a new companion novel to his Newbery Award-winner, "The Crossover,"" illustrated with striking graphic novel panels. Pre-order today
The book is devoted to two subjects representing some of the most challenging areas of computational methods of differential geometry and mechanics of shells; it also includes a CD-ROM with complete source codes (over 20,000 lines) in C/C++, ready to be compiled and used. (1) A new method is presented, allowing construction of the lines of principal curvature on arbitrarily complex curved surfaces. The authors explain in detail the developed algorithms and their implementation. (2) The book describes application of the developed algorithms to the Finite Element Analysis of thin shells, allowing to obtain high-quality numerical results, especially for the displacements and for the components of the stress tensor. All source codes are well commented. The book also includes several examples with known analytical solutions. The developed codes deliver solutions demonstrating excellent correspondence between the analytical and numerical results. This book is also available in paperback (listed separately).

The book successfully addresses two main subjects:
- The development of a new method for the construction of the lines of principal curvature on arbitrarily complex curved surfaces,
- The formulation and implementation of a new 9-noded shell finite element that delivers high-quality numerical results, particularly for displacements and stresses.
Both the theoretical basis and the developed algorithms are thoroughly explained and fully implemented in the provided source codes.
As a professional working in the implementation of finite element analysis, I was most impressed by the extensive coverage of particular cases in the algorithms, putting in evidence that the authors devoted much effort to implement and test their formulations to obtain solid and reliable results. This aspect sets this work apart from most textbooks where you get the general idea but are left with many exceptions to solve on your own.
Furthermore, this book provides an introduction to differential geometry, as well as the mathematical fundamentals of the theory of thin shells, making it a good reference for a broad range of people, from students to engineering professional working with shell finite elements.
I especially want to mark chapters, which are allocated for FEM. They are very helpful for understanding method's application for engineering needs, as FEA of thin shells. There is short description of the FEM steps and principles, in relation of quadrilateral finite elements. Chapter 5 contains very visual explanation of the algorithm for constructing the lines of principal curvature at any point on the FE surface. Numerical examples at the end and source codes make the book a complete resource on meshing algorithms for shells.
