  • Prof. John Vlachopoulos, one of the founding members of our society, has received the "Stanley G. Mason award" of the Canadian Society of Rheology for his contributions to research, industrial consulting and teaching in rheology of polymers (photo). The award is named after Canada's rheology pioneer, the late S.G.Mason, renowned for numerous contributions in the microrheology of suspensions and particulate flows. The award is presented every other year. Previous winners include J.M. Dealy, P.J. Carreau, M.C. Williams, and D.F. James. Evan Mitsoulis, one of his first PhD students and Professor now at the National Technical University of Athens, gave the talk at the award ceremony on Nov. 23, 2007 at McMaster University, Hamilton, Ontario, Canada.

    John Vlachopoulos was born in Volos and studied Chemical Engineering at the Technical University of Athens (ΕΜΠ - NTUA). He received his D.Sc at Washington University in St. Louis, Missouri, USA. He has been in the faculty of MacMaster University since 1968 (yes, this is almost forty years to date). He is the director of the Centre for Advanced Polymer Processing and design (CAPPA-D). His main interests are in polymer processing and its modelling. Over the years he has supervised 17 PhDs and 32 Masters, and from his students he has produced 8 Professors who serve now in several Universities (McMaster, AUTH, NTUA, Waterloo, AmirKabir, Queen's, Calgary and Chang Gang).

    Vlachopoulos has published more than 123 papers, has presented around 100 papers in conferences, he is the co-editor/author in 6 books and lecture notes, he has contributed chapters to 13 books and several articles of general interest. He has written over 100 confidential consulting and research reports to corporations and there have been over 300 presentations given by students under his supervision (data from Mitsoulis, 11/2007).

    Vlachopoulos has been very prolific in giving seminars and presentations in several languages (6 different languages so far and the list is growing): ENGLISH (several hundred presentations), GERMAN (dozens), FRENCH (dozens), SPANISH (dozens), GREEK (a few), PORTUGUESE (two), and getting ready to lecture in a couple of more languages. I have personally heard him trying to communicate with reasonable success in dutch, italian and chinese (and somewhat less success in slovenian). John has presented his INTENSIVE SHORT COURSE ON POLYMER RHEOLOGY and PROCESSING 61 times since 1987 in 16 countries (the 62nd will be presented in BRUSSELS, BELGIUM, the 63rd in VALENCIA, SPAIN, the 64th in BURLINGTON, ON, and the 65th in BAHRAIN in 2008).

    One of the things that Vlachopoulos is known for is the software packages that he has developed. He has founded the company POLYDYNAMICS Inc. which sells now at least 10 different software packages for polymer processing, from a general-purpose FEM flow calculations package to specialised packages for extrusion, thermoforming, rheology etc.

    We wish John Vlachopoulos the very best for the years to come with ever more awards, new ideas, papers, software packages and world-wide seminars, the things that he likes to do the most. Some more photos from the ceremony are here: with other award recipients, with friends and one more.

  • Mini-Symposium: Tribute to Kirk C. Valanis

    Sixteenth ASCE Engineering Mechanics Conference (EM2003), University of Washington, Seattle, Washington, July 16-18, 2003
    As a tribute to Dr. Kirk Valanis' visionary and lasting contributions in mechanics a Mini-Symposium comprising of three sessions was held at the 16-th ASCE Engineering Mechanics Conference. The Symposium provided a forum for discussion of new, as well as, non-traditional developments in solid mechanics, specifically in the areas of fundamental constitutive theory, thermodynamics of materials and its applications to constitutive theory, plasticity theories - including finite stain theories - and plasticity models, internal variable theory, nano- and micromechanics, material science and engineering.

  • Dr. Kirk Valanis has been elected as Honorary Member of the HSR (Sept. 2002). He has also delivered a Keynote Lecture in the 4th Conference of the Society in Athens, 2004.
    The HSR has so far three Honorary Members. The other two are Professor Andy Acrivos and Dr. Louis Zappas.

  • The 2001 National Medal of Science Laureate in Engineering (USA) went to Professor A. Acrivos

    Professor Andreas Acrivos, a honorary member of the Hellenic Society of Rheology (HSR), is the 2001 National Medal of Science Laureate in Engineering, USA's highest science and technology honor and distinction!

    The entire family of the Hellenic Society of Rheology, all his colleagues and friends that participated in the 3rd HSR meeting in Patras honoring him and surely the many other friends of Professor Andreas Acrivos worldwide, would like to express him their sincerest congratulations for this outstanding honor and recognition, and wish him many more in the future!



  • Professor Antony Beris appointed as the first Arthur B. Metzner Professor

    Professor Antony Beris, member of the Hellenic Society of Rheology (HSR), has been the first Arthur B. Metzner Professor of Chemical Engineering at the University of Delaware!

    The new professorship was endowed by the Gore family at the University of Delaware earlier this year to honor Arthur B. Metzner, H. Fletcher Brown Emeritus Professor of Chemical Engineering, who went to the University of Delaware in 1953 and chaired the Department of Chemical Engineering from 1970-77. Professor Metzner has had numerous contributions to rheology (being among the first to study drag reduction, flow-induced phase separations, processing instabilities, among others) has been awarded numerous awards, like the Bingham medal and has been the editor of the Journal of Rheology, among others.

    Professor Beris, a graduate of the National Technical University of Athens, joined the UD faculty in 1985, after receiving his doctoral degree from the Massachusetts Institute of Technology. His research focuses on the development and application of numerical methods to fluid mechanics and transport phenomena with emphasis to polymeric materials and materials processing, and in the use of parallel computer architectures in high performance computing. He is also active in the modeling and simulation of complex systems, such as polymer solutions and melts, guided by principles of non-equilibrium thermodynamics. Most recently he worked to develop a first principles simulation of the polymer-induced drag reduction in turbulent flows.



  • Award of Honorary Degree to Professor A. Acrivos

    The Hellenic Society of Rheology is pleased to announce that Professor A. Acrivos has been awarded a honorary degree from the City College of the City University of New York.
