Upon the request of the International Union of Theoretical and Applied Mechanics (IUTAM) the Swedish National Committee for Mechanics organized a colloquium on fatigue, which was held at the Royal Institute of Technology (Kung . Tekniska Hogskolan) in Stock holm, May 25-27, 1955. 35 lectures were delivered, principally dealing with problems of statistical and basic nature. Among the topics were to be found statis tical theory of fatigue, cumulative damage, mechanism of fatigue, me tallurgical aspects on fatigue, velocity of fatigue cracks, fatigue at elevated temperature, and fatigue at...

Bluff-body wakes play an important role in many fluid dynamics problems and engineering applications. This book gives and up-to-date account of recent results obtained in the study of bluff-body wakes. Experimental, theoretical and numerical approaches are all comprehensively covered and compared. Topics of particular interest include hydrodynamic instability analyses, three-dimensional pattern formation problems, flow control methods, bifurcation analyses, numerical simulations and turbulence modelling. The main originality of thisvolume is that recent conceptual advances made to describe...

Processes taking place in the contact of two bodies and having an influence on strength and service life of machinery or of the whole structure have been in the interest of physicists and engineers for a very long time. The first scientific base had been created by H. Hertz (see Hertz. H.: tJber die Beruhrung. fester elastischer Korper. J. reine und angewandte Mathematik. 1882. 92. pp. 156-171 ) more than one hundred years ago. Since that time (proportionally to the need of industry) countless numbers of other studies have originated, But practice always has been an inspiration for the...

The proposal for a Symposium on high temperature effects in solids originated in 1964, at which time a pilot committee, headed by Professor F. K. G. ODQVIST, was formed. Upon the recommendation of this com- mittee, a site for the Symposium and a Scientific Organizing Committee were chosen, and some guidelines delineating the field to be covered were established. The Symposium was held at the National Engineering Laboratory in East Kilbride (Glasgow), Scotland, from June 25 to 28, 1968. The Scientific Organizing Committee was composed of the following mem- bers: Professor B. A. BOLEY, Chairman...

The IUTAM Symposium on Constitutive Relation in High/Very High Strain Rates (CRHVHSR) was held October 16 - 19, 1995, at Seminar House, Science University of Tokyo, under the sponsorship of IUTAM, Japan Society for the Promotion of Science, The Commemorative Association for the Japan World Exposition (1970), Inoue Foundation for Science, The Japan Society for Aeronautical and Space Sciences, and Science University of Tokyo. The proposal to hold the symposium was accepted by the General Assembly of IUT AM held in Haifa, Israel, in August 1992, and the scientists mentioned below were appointed...

At its meeting on April 23, 1965 in Paris the Bureau of IUTAM decided to have a Symposium on the Irreversible Aspects of Continaum Mechanics held in June 1966 in Vienna. In addition, a Symposium on the Transfer of Physical Characteristics in Moving Fluids which, orig inally, had been scheduled to take place in Stockholm was rescheduled to be held in Vienna immediately following the Symposium on the Irre versible Aspects of Continuum Mechanics. It was felt that the subjects of the two symposia were so closely related that participants should be given an opportunity to attend both. Both...

Depuis Ie lancement de SPOUTNIK I par l'Union Sovietique Ie 4 Octobre 1957, des experiences humaines de Mecanique celeste de cette sorte ont ete repetees it de nombreuses reprises en U. R. S. S. et aux U. S. A. En 1961, sur ma proposition, l'Union Internationale de Mecanique tMorique et appliquee retint l'idee de consacrer en 1962 un Symposium special it la confrontation des resultats des experiences sovietiques et americaines en vue d'en tirer Ie maximum d'enseignements sur la question fondamentale suivante concernant la Dynamique des satellites artificiels) de la Terre: quelles sont la...

The management of vortices and separation behind the bodies at high angles of attack is important for high maneuvrability of airplanes and other fluid dynamic apparatus. The recent international developments in the fundamental sciences and the application to the control of fluid behaviours were presented at the IUTAM Symposium on Fluid Dynamics of High Angle of Attack in September 1992 in Tokyo and documented in this volume.

In 1976 a similar titled IUTAM Symposium (Structure of Turbulence and Drag Reduction) was held in Washington . However, the progress made during the last thirteen years as weil as the much promising current research desired a second one this year. In Washington drag reduction by additives and by direct manipulation of the walls (compliant walls and heated surfaces) were discussed. In the meantime it became evident that drag reduction also occurs when turbulence is influenced by geometrical means, e.g. by influencing the pressure distribution by the shape of the body (airfoils) or by the...

The Symposium originated in a proposal made in 1969 by Professor A. A. Ilyushin, Moscow. A study group (chairman J. Hult), appointed by the General Assembly of IUTAM in 1971, suggested in areport to the Bureau of IUTAM in 1972 that the following topics should form the basis of the scientific program: 1) Limits of linearized theories and effective versions of the non-linear theory of viscoelasticity 2) Theory of experimental studies in linear and non-linear viscoelasticity aiming at the determination of consti- tutive equations and conditions of strength and failure under an arbitrary...
