While there are many books about Finite Element Methods, this is among the first volume devoted to the application of FEM in spring design. It has been compiled by the working group on Finite Element Analysis of Springs, sponsored by the Japan Society of Spring Research. The monograph considers the wide spectrum of spring shapes and functions, enabling readers to use FEM to optimize designs for even the most advanced engineering cases. This book provides the theoretical background and state-of-the-art methodologies for numerical spring analysis. It also employs and explains many real-world design examples, calculated by commercial software and then compared with experimental data, to illustrate the applicability of FEM to spring analysis. Engineers already dealing with spring design will find this an excellent means of learning how to use FEM in their work, while others will find here a helpful introduction to modern spring technology and design.

Materials for springs is basically intended for engineers related to spring materials and technologies who graduated from metallurgical or mechanical engineering courses in technical high school, or in other higher engineering schools, as well as those who are related to the purchase or sales of spring materials.

The first chapter introduces into the fundamental selection processes of spring materials including the information sources on materials database. It is followed by the basic mechanisms and theories of spring failures such as fatigue fracture, creep/stress relaxation and stress corrosion cracking of metallic materials.

The focuses of the second chapter is put on ferrous and non-ferrous metallic materials, including some materials developed in these two decades, such as high strength automobile suspension steels etc.

In the third and fourth chapters, polymer materials, FRP (Fiber Reinforced Plastics), ceramics and C/C composite materials are the main subject respectively.

In the fifth chapter, lists of Japanese spring material manufacturers and their material grades being produced, comparisons of spring materials in the Japanese Industrial Standards with some other foreign standards, etc, are summarized.

The Japanese original edition of "FEM for Springs" was published in 1997, to com memorate the 50th anniversary of Japan Society for Spring Research (JSSR). While there have been many books published about Finite Element Method (FEM), this book was among the first to address the application of FEM to spring design. When asked about springs, one might imagine a mere shape of helical coil. How ever, there are many more varieties of shapes and functions in the application of springs. Consequently, some are very difficult to calculate by design formula. FEM gives the solutions to those advanced engineering cases. Nowadays, it is strongly desired to have a design method for springs as a com mon base from a global point of view. Under these circumstances, JSSR planned to publish an English version of "FEM for Springs." By improving the contents and adding many examples, this book, FEM for Springs, has been brought to comple tion. It is a truly significant event. I am confident that this book is suitable for engineers in worldwide industrial sectors and for college students as well."
