{"title":"Nano-scale fracture phenomena and TeraHertz pressure waves as the fundamental reasons for geochemical evolution","authors":"A. Carpinteri, O. Borla","doi":"10.3233/SFC-180220","DOIUrl":"https://doi.org/10.3233/SFC-180220","url":null,"abstract":"TeraHertz vibrations and pressure waves are produced at the nano-scale in solids and fluids by fracture and cavitation, respectively. They present a frequency that is close to the resonance frequency of the atomic lattices and an energy that is close to that of thermal neutrons. Original experiments performed on non-radioactive rocks under mechanical compression loading have shown repeatable neutron emissions in correspondence to microand macro-fracture. After these experiments, a considerable reduction in the iron content of the crushed rocks appears to be consistently counterbalanced by an increase in Al, Si, and Mg contents. At the same time, significant measurements of neutron emissions are observed at the Earth’s Crust scale before and during seismic activity. In addition, several data coming from geochemistry and geomechanics have recently emphasized how tectonic activity should have been strictly connected to the most important changes in the Earth’s Crust chemical composition over the last 4.5 Billion years. On these bases, the hypothesis of a new kind of low energy nuclear reactions finds confirmation and could be considered as a valid explanation for the geologic evolution of the Earth’s Crust, Ocean, and Atmosphere. The same phenomenon appears to have occurred also in the chemical evolution of other planets of the Solar System like Mars, and of the Sun itself.","PeriodicalId":41486,"journal":{"name":"Strength Fracture and Complexity","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/SFC-180220","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43109035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The fracture of thermosetting epoxy polymers containing silica nanoparticles","authors":"F. J. Guild, A. Kinloch, K. Masania, S. Sprenger, A. C. Taylor","doi":"10.3233/SFC-180219","DOIUrl":"https://doi.org/10.3233/SFC-180219","url":null,"abstract":"An epoxy resin, cured with an anhydride, has been modified by the addition of silica nanoparticles. The particles were introduced via a sol-gel technique which gave a very well dispersed phase of nanosilica particles, which were about 20 nm in diameter, in the thermosetting epoxy polymer matrix. The glass transition temperature of the epoxy polymer was unchanged by the addition of the nanoparticles, but both the modulus and toughness were increased. The fracture energy increased from 77 J/m for the unmodified epoxy to 212 J/m for the epoxy polymer containing 20 wt.% of nanosilica. The fracture surfaces were inspected using scanning electron and atomic force microscopy, and these microscopy studies showed that the silica nanoparticles (a) initiated localised plastic shear-yield deformation bands in the epoxy polymer matrix and (b) debonded and allowed subsequent plastic void-growth of the epoxy polymer matrix. A theoretical model for these toughening micromechanisms has been proposed to confirm that these micromechanisms were indeed responsible for the increased toughness that was observed due to the presence of the silica nanoparticles in the epoxy polymer. _________________________________________________________________________","PeriodicalId":41486,"journal":{"name":"Strength Fracture and Complexity","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/SFC-180219","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46804168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 1969 ICF was established in Brighton, UK with a governing constitution via the Statutes & Bye-Laws. These Statutes & Bye-Laws are indeed an evolving, living document with progressive revisions followed over the decades since 1969. Many evolutions in developing our now mature ICF culture and modus operandi have occurred over the years. There will be others in the challenging era ahead 2017-2029 via ICF14, ICF15, ICF16 & ICF17 but we might highlight: (1) The Gold & Silver Medals introduced in 2009 at ICF12 as an important extra-statutory evolution of ICF for the benefit of our global brand via AwardCo; (2) The Honour Lectures introduced in 1977 at ICF4 via Ashby/Bilby and followed to the highest standard therefrom; (3) The MoU System to assure the autonomy and independent organization of our quadrennials in the context of the ICF Culture introduced at ICF12 via the Canadian Government and developed for ICF13, ICF14 & ICF15; (4) The Quadrennials Regional Rotation guideline introduced at ICF6 in 1984 to ensure wide global participation; (5) The Interquadrennials Programme initiated in 1983 in Beijing after ICF5 and continued very actively since ICF12 with various ICF regions; (6) The Enlarged Portfolio-Based ExCo introduced at ICF13 for wider representation and \"New Blood\"; (7) The Enhanced Accreditation of voting Council members to be introduced at ICF14 via NomCo; (8) The Multi-Stranding of the original ICF micro/macro brand from ICF4 and progressively at each quadrennial including geophysics, biomedical, bio-engineering, non-metallics, computational mechanics, adhesion, nano-scales, sustainabilty, energy, education, politics/society, safer engineering, risk & disaster analysis; (9) The ICF Website and accessibility to all our Proceedings introduced via IGF after ICF12; (10) The Regional Groups in the Far-East, Iberia/Latin America, Africa, India, Australasia, Europe, Canada, Egypt and variously from 1976 onwards originally via Dominique in Compiegne, France and EGF; (11) The Chief Executive-Treasurer role in structured leadership since ICF6; (12) The ICF Culture of friendly, human, transparent, democratic, harmony-oriented respecting past contributions of “heavy-lifters” via emeritus standing and FICF election towards Safer, Sustainable Technology for the common good.","PeriodicalId":41486,"journal":{"name":"Strength Fracture and Complexity","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/SFC-180215","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44759250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
