The route to J-integral by prof. James Rice

Professor James Rice, world-leading expert in the field of mechanics, recently visited the Faculty of Mechanical Engineering in Belgrade, where he held a heavily attended lecture devoted to the 50th anniversary of his paper about the J-integral. The lecture was a part of the international fracture mechanics Summer School, an event that accompanied the 22nd European Conference on Fracture which is currently taking place at the “Metropol” hotel.

James rice is a professor of engineering sciences and geophysics at the Harvard University in the USA. Fifty years ago he formulated one of the most important fracture mechanics parameters, the so-called J-integral, which is defined as one of the means for calculating of the change in fracture surface strain energy, which is of great significance in structural integrity assessment. During his lecture, Professor Rice also mentioned some of the applications of the J-integral, which was particularly important to some of the Summer School participants.

The concept of the J-integral is indubitably one the most important scientific contributions of prof. Rice. During the last few decades, his research was focused on the subjects in the field of geomechanics – glaciers, earthquakes and other important aspects of fracture, which he specifically spoke of in his introductory lesson at the opening of the 22nd European Conference on Fracture.

After the previous conferences held in Trondheim and Catania, this year’s Summer School took place on 25th and 26th of August in Belgrade. It was organised by the Structural Integrity and Life Society “Prof. dr Stojan Sedmak”, in cooperation with the Faculty of Mechanical Engineering in Belgrade.

The Summer School was attended by around 150 participants. Young researchers, engineers and PhD students from all over the world had the opportunity to learn about the latest research results in the field of fracture mechanics, by listening to lectures held by world-leading experts.

Prof. John Landes from the USA spoke about the topic of “Basics of experimental fracture mechanics, linear elastic and elastic-plastic growth”. The lecture held by prof. Francesco Iacoviello from the Cassina University in Italy was about the “Basics of experimental fracture mechanics, fatigue crack growth”. Prof. Bamber Blackman from the Imperial College in London spoke about the deforming and failure of polymers and composites, whereas the subject of interface fracture mechanics was covered by prof. Leslie Banks-Sills from the Tel Aviv University in Israel.

The first international fracture mechanics Summer School, known as “The Introduction to Fracture Mechanics and fracture-safe design was organised in 1980 by the Faculty of Technology and Metallurgy and the GOŠA Institute, under the initiative of prof. Michael Wnuk (Wisconsin University, Milwaukee) and prof. Stojan Sedmak (Faculty of Technology and Metallurgy, Belgrade). The Summer School was attended by a total of 63 participants, and 20 lectures were held, one of which was an invited lecture.

ECF 22 – Global scientific elite in Belgrade

The problems of fracture mechanics and structural integrity were the central topic of the 22. European Conference on Fracture, which takes place in Belgrade, from 27th to 31st of August this year. More than 500 participants from all over the world will consider the most important aspects of this field of mechanics, which studies problems related to cracks and their effects on the behaviour of materials and structures. The conference was organised by the Structural Integrity and Life Society “Prof. dr Stojan Sedmak”, in cooperation with the European Structural Integrity Society (ESIS).

This conference on fracture, the first to be held in Serbia after 26 years, was officially opened on Monday, August 27th at the Metropol Hotel in Belgrade. The conference opening was attended by the representative of relevant ministries within the Government of the Republic of Serbia, as well as the representatives of the University of Belgrade, the scientific and industrial community and many other respected guests from our country and abroad.

On behalf of the Ministry of education, science and technological development of Republic of Serbia, the guests were greeted by the State Secretary, prof. dr Viktor Nedović, who took the opportunity to point out the importance of this conference not only for Serbia, but also for the region as a whole. On behalf of the Faculty of Mechanical Engineering of University of Belgrade, the guests were greeted by prof. dr Nenad Zrnić, the newly elected rector for international scientific cooperation of the University of Belgrade, and the vice-dean of international cooperation at the Faculty of Mechanical Engineering. The guests were also addressed by the conference chairman, prof. dr Aleksandar Sedmak, who is also the president of the Structural Integrity and Life Society “Prof. dr Stojan Sedmak”, and prof. dr Leslie Banks-Sills, the president of ESIS.

The work section of the conference was opened by a lecture held by prof. dr James Rice, a world-leading expert who formulated one the most important parameters in fracture mechanics, the J-Integral, 50 years ago. Prof. Rice teaches engineering sciences and geophysics at the Harvard University, and has been involved in geomechanical studies (glaciers, earthquakes…) for the past few decades. His lecture on this subject attracted major attention from the conference participants.

The first day of the conference was marked by two additional lectures. Prof. dr Jovo Jarić, a Serbian representative, spoke about the topic of “Conservation laws of the J Integral type”, whereas his colleague from Croatia, prof. dr Dražan Kozak held a lecture titled “Integrity of the pipeline by using the pipe-ring testing, part 1”.

On the second day, the plenary lectures were held by prof. dr Yoshi Hong from China, on the topic of “The State of the Art in Very-High-Cycle Fatigue Research”, professor Uwe Zerbst on the topic of “Application of fracture mechanics to S-N curve prediction”, professor Meinhard Kuna on the topic of “Micromechanical modeling of fracture in metallic materials”, and professor Nenad Gubeljak from Slovenia, who presented a lecture named “Integrity of pipeline by using pipe-ring testing, Part 2”.

The latest results and scientific breakthroughs in the field of fracture mechanics and structural integrity will be the focus of the conference in the following days. “Soft Network Composite Materials with Deterministic and Bio-Inspired Designs” was the subject of a lecture held by prof. Yonggang Huang from the USA. His compatriot, prof. Robert Ritchie will speak about the “Damage tolerance in Biological and Metallic Materials”. The subject that will be presented by prof. William Curtin from Switzerland is “Mechanisms of Hydrogen Embrittlement: Insights from Atomistic Studies”, whereas prof. Takayuki Kitamura from Japana will speak about the “Challenge toward Nanometer Scale Fracture Mechanics”.

Mini-symposia involving the fracture mechanics topics which are currently of most interest, above all related to hydrogen embrittlement, which represents the most significant problem related to corrosion failure, will be organised as a part of the conference.

The organisation of the 22nd European Conference on Fracture was financially supported by the Ministry of education, science and technological development of Republic of Serbia, EPS and other sponsors (Rumul, Messer and Sobriety), and significant support was provided by the Faculty of Mechanical Engineering of University of Belgrade, which co-organised the Summer School of fracture mechanics.
