Evaluation of Scientific Sources in Mechanics [PDF ebook] 
Heiberg’s Prolegomena to the Works of Archimedes and Hellinger’s Encyclopedia Article on Continuum Mechanics

Part I. The loss and reconstruction of scientific sources with a particular reference to mechanics and theory of materials: The loss and reconstruction of the article by Hellinger in the Encyclopaedia of athematics.- The loss of the works by Archimedes and their reconstruction by Heiberg.- The loss of the works by Piola and the Italian tradition of Mechanics.- Part II. The recovery of the works by Hellinger, Archimedes, Piola and Heiberg: The monumental translation by Heiberg and his (nearly lost) commentaries written in Latin.- The masterpiece by Hellinger and its influences on modern continuum mechanics.- The forgotten Piola.-Part III. The recovery of the work by Archimedes and the role of Heiberg.- Part IV. The different ways of evaluating the importance of sources: why bibliometric indices?

Francesco dell’Isola has been Full Professor at the Department of Structure and Geotechnical Engineering, Sapienza University of Rome, Italy, since 2006 and Full Professor at the Department of Civil Engineering (DICEAA), University of L’Aquila, Italy, since 2016. In 2016, he also became Director of the International Research Center M&Mo CS (University of L’Aquila). Since 2015, he has been Responsible Italian Scientific Expert at the Laboratoire International Associé (LIA) Coss&Vita, a French-Italian international laboratory. His research activities chiefly focus on the synthesis and design of metamaterials and on generalized models in continuum mechanics.Simon R. Eugster is Senior Lecturer at the Institute for Nonlinear Mechanics (INM), University of Stuttgart, Germany, since 2020. He received his MSc and Ph D degree from ETH Zurich, Switzerland, in 2009 and 2014. In 2014, he became Lecturer at the INM at the University of Stuttgart. His research is focused on the mathematicaldescription of highly deformable elastic structures with a particular interest in mechanical metamaterials as well as soft robotics and multibody dynamics.Mario Spagnuolo is Researcher at the Department of Civil and Environment Engineering and Architecture (DICAAR), University of Cagliari (Italy) since 2019. He obtained his Ph D in Paris at the Université Sorbonne Paris Cité, where he was granted a Marie Sklodowska Curie European scholarship. His research mainly focuses on structural mechanics and continuum mechanics, with a particular interest in the synthesis and design of metamaterials.
