Title: Fatigue assessment of large structures: open issues and possible solutions 

Abstract: Fatigue design of large structures is still an open problem which affects designers all over the world. The aim of the talk is to give a brief overview of open issues and possible design solutions that can help the designers to face these challenges. Advanced applications of local approaches will be discussed in this regard with particular attention to energy based approaches. 

Dorin Radu, Professor

His research interest is in structural integrity, assessment and optimization of existing structural elements, new materials for sustainable constructions, neural networks applied in civil engineering. He is the author of several books, conference papers and large number of articles published in high ranked journals.

Title: Structural integrity assessment – part of a sustainable development 

Abstract: The in-service safety assessment of existing steel structures is a complex problem which requires interdisciplinary approaches – from civil engineering application using Eurocodes or European recommendation for fatigue life estimation, up to an in-depth assessment by means of fracture mechanics. The scope of the presentation is to describe possible solutions for assessment of existing steel structures using Engineering Critical Assessment approach and applying to several study cases.

Francesco Iacoviello, Professor

University of Cassino and Southern Lazio, Department of Civil and Mechanical Engineering, Italy

Biography:

Francesco Iacoviello is full professor of Metallurgy at the Faculty of Engineering of the University of Cassino and Southern Lazio. He was President of the Italian Group of Fracture - IGF (2009-2021), President of the European Structural integrity Society – ESIS (2018-2022), Vice-President of the International Congress on Fracture (2017- 2023).

He is Director of the International Congress on Fracture, Editor in Chief of Fracture and Structural Integrity and of Procedia Structural Integrity and Deputy Rector for Services and Infrastructures at the University of Cassino and Southern Lazio. His main research fields concern the analysis of fatigue crack propagation resistance and damaging micromechanisms of stainless steels, ductile cast irons, Al and Ti alloys, shape memory alloys, additively manufactured alloys and Zn coated steels, the investigation of stainless steels hydrogen embrittlement mechanisms and the analysis of stainless steels localized corrosion micromechanisms. 

Title: Ductile Cast Irons: porous steels or natural composites? 

Abstract: In 1943 and in 1948, the addition of magnesium and of cerium, respectively, allowed to obtain graphite elements embedded in ferritic-pearlitic matrix with mechanical properties that were analogous to those offered by malleable cast iron, but with a reduced production cost. In the last decades, the interest on ductile cast irons (DCIs) strongly increased and many different grades were optimized in order to offer a wider range of properties depending both on the chemical composition and on the heat treatment. The increasing industrial interest on DCIs offered a strong motivation to improve the knowledge of the damaging mechanisms of these grades, considering both their peculiar microstructure (a sort of “natural” composite, with graphite nodules embedded in a metallic matrix) and the different loading conditions (static, quasi static, cyclic etc.). A crucial point in the analysis of the damaging micromechanisms in DCIs concerns the role played by the graphite nodules. The aim of this presentation is to offer an overview of the different proposed damaging mechanisms and the different roles that can be assigned to the graphite nodules.

Title: Non-standard tensile and bending ring specimens for fracture examination of pipeline materials

Abstract: In the previous period, a significant number of studies worldwide have dealt with determination of fracture resistance of the pipeline materials. The main focus is on the thin-walled pipes, because it is typically difficult, or impossible, to fabricate standard fracture mechanics specimens such as Single Edge Notch Bending (SENB) or Compact Tension (CT). Therefore, two non-standard specimen geometries developed in the previous period will be presented and discussed. Both of them are ring-shaped, and the difference is in the loading type: tension in the case of Pipe Ring Notch Tension (PRNT) specimens or bending in the case of Pipe Ring Notch Bending (PRNB) specimens.
