Fracture and Structural Integrity, 41 (2017); ISSN 1971-9883 X researcher whose pioneering contributions have had lasting impact on engineering applications of fracture theories. Previous recipients of this medal are Professors Paul C. Paris (2009), James R. Rice, and John A. Hutchinson (2013). Paul C. Paris Gold Medal honours the many pioneering contributions of Prof. Paul C. Paris to the field of Fracture Mechanics. His contributions in field of sub-critical crack growth include the discovery of the “Paris-Law” for fatigue crack growth. This award is presented to senior researchers whose pioneering contributions have had a lasting impact on structural integrity assessment methods. Previous winners of this medal include Professors Alberto Carpinteri and Y. Murakami (both in 2013). Constance F. Tipper Silver Medal honours the memory and contributions of Constance Tipper who was a true pioneer in the field of fracture and the author of the popular book “The Brittle Fracture Theory”. The silver medal is awarded to a mid-career scientists/engineers who have made significant contributions in any aspect of research in the field of fracture. Previous recipients are Professors Julia King (Baroness Brown of Cambridge), Diane Lados, and Namrata Gundiah (all 2013). In 2017, ICF named six scientists to receive its highest honour, the gold medals, and two mid-career scientists to receive silver medals. These medals will be awarded in a ceremony to be held at the Fourteenth International Conference on Fracture, ICF14, in Rhodes, Greece between June 18-23, 2017 (see www.icf14.org ) for details of the conference. Professors A. Toshimitsu Yokobori (Japan) and Emmanuel Gdoutos (Greece) are the co-recipients of the 2017 ICF Takeo Yokobori Gold Medal A. Toshimitsu Yokobori Emmanuel E. Gdoutos Professor Yokobori, Jr. is Professor Emeritus of Tohoku University and Visiting Professor at Teikyo University in Japan. He has made seminal contributions in multiscale fracture analyses across nano, meso, to macro scales and is widely recognized for his contributions. His dislocation dynamics theory of fatigue crack growth and threshold stress intensity factor is cited in many books and review articles and is popularly known as Yokobori’s theory. He has also contributed extensively to characterizing fracture and crack growth at elevated temperatures and has led several national programs in these areas. The Q* concept that he co-authored with his father, Prof. Takeo Yokobori, is based on a thermally activated theory of creep crack growth has enabled the prediction of creep crack growth rate and fracture life. Prof. Yokobori has served as the Secretary General of ICF continuously since 2001 and as a member of the ICF Council from Japan since 1989. He was named Honorary Fellow of ICF in 2013. Professor Emmanuel E. Gdoutos serves as Full Member of the Academy of Athens, the most prestigious academic institute in Greece. He has made seminal contributions in the field of Experimental Mechanics, Fracture Mechanics, Nanotechnology and their applications to composite materials and sandwich structures for civil engineering structures. He has authored/co-authored more than 300 technical papers and 40 reference and text books, among them the book “Fracture Mechanics – An Introduction” used for fracture mechanics courses worldwide. He has served as President/Chair of several technical societies including the European Structural Integrity Society and conferences. He is member of European, American and foreign national academies and received awards from international societies. He was awarded a Doctorate Honoris Causa from the Russian Academy of Sciences and from the University of Nis, Serbia. He is the Sr. Vice President and Fellow of ICF and is the Executive Chair of ICF14 in Rhodes, Greece in June 2017.
