Started in 1976, the European Conference of Fracture, (ECF) organized under the auspices of the European Structural Integrity Society (ESIS), takes place every two years in a European country. The 16th European Conference of Fracture (ECF16) was held in Alexandroupolis, Greece, July 3-7, 2006. ECF16 focused on all aspects of structural integrity with the objective of improving the safety and performance of engineering structures, components, systems and their associated materials. Emphasis was given to the failure of nanostructured materials and nanostructures including micro- and nano-electromechanical systems (MEMS and NEMS). The technical program of ECF16 was the product of the hard work and devotion of more than 150 leading experts in the world. This volume contains two-page abstracts of the 698 papers presented at ECF16. The accompanying CD attached to the back cover of the book contains the full length papers. The abstracts of the fifteen plenary lectures are included in the beginning of the book. The remaining 683 abstracts are arranged in 25 tracks and 35 special symposia/sessions with 303 and 380 abstracts, respectively. The papers of the tracks have been contributed from open call, while the papers of the symposia/sessions have been solicited by the respective organizers. Both tracks and symposia/sessions fall into two categories, namely, fracture of nano and engineering materials and structures with 88 and 595 papers, respectively. The volume contains the latest research work of renowned experts in the area of failure of engineering materials and structures and is useful for the student, the engineer and the researcher who wants to get an integrated picture of the recent developments in the area of fracture mechanics and fatigue.
