This society is an established forum for distinguished material scientists, bioengineers, molecular and cellular biologists, bone biologists, orthopedic surgeons, clinicians and manufacturers, to gather together and discuss the latest achievements in the field of Bioceramic materials.
Ceramic materials can also be used in tissue engineering in association to growth factors and cells.
We hope that in this book the reader will find inspiration to further advance hi s research results with a beneficial effect on the quality of life of the patients.

Preface ICSAM 2012, the 11th International Conference on Superplasticity in Advanced Materials, was held in Ecole des Mines Albi, France, from the 3 rd to 5 th July 2012.
More than 120 scientists form universities, research centers and industry from 17 th countries came together to report and discuss on recent advances in the field of superplastic forming. 71 oral contributions and 14 posters were presented in 21 sessions over the 3 days.
Within these, 62 full papers were submitted and peer reviewed and are published in this book as a special edition of Material Science Forum Journal, by Trans.
During the conference the best poster Award, sponsored by AIRBUS, was attributed to Toshiaki Manaka, a young researcher form the Graduate School of Science and Engineering, Ibaraki University, Japan.

With the efforts of researchers, many effective methods are advanced and some excellent simulation and visualization software is developed, such as GOCAD, SURPAC, MICROMINE, and VULCAN and so on.
In geotechnical engineering the other most common numerical software is FLAC3D and ABAQUS.
FLAC3D is the most famous numerical calculation software for geotechnical engineering.
It has outstanding ability in nonlinear calculation, so it is often used in geotechnical engineering.
