Bulletin No. 29 ITC 86 Review The First International Conference on Ice Technology was held on the campus of MIT during 10-12 June 1986. The Conference was preceded and followed by Tutorials on Monday 9 June and Friday 13 June. On the morning of 9 June, the tutorial was presented by Dr A. M. Vinogradov of the University of Calgary on Computational Methods in Ice Mechanics with two separate lectures on (1) Constitutive Modelling of Ice and (2) Computational Methods in the Deformation Analysis of Floating Ice Sheets. There was a healthy number of participants for this tutorial. During the afternoon, Mr Peter G. Noble of the Marine Technology Corporation, Houston, Texas, presented two lectures on Model Testing and Instrumentation Techniques. The Conference was opened on Tuesday by RADM Robert L. Johanson, District Commander of the First Coast Guard District at Boston, who was introduced to the audience by Professor Francis T. Ogilvie, Head of the Department of Ocean Engineering at MIT. This was followed by a Keynote Address from Dr George Ashton, an eminent scientist from the US Army Cold Regions Research and Engineering Laboratories (USACRREL) on Perspectives in Ice Technology. The plenary sessions then commenced with some opening remarks by Dr Carlos A. Brebbia, Chairman of the Computational Mechanics Institute, Southampton, the sponsoring organisation. He took the opportunity to present a plaque to Professor J. J. Connor of the Department of Civil Engineering at MIT in recognition of his contribution to advances in engineering mechanics. A total of 44 papers were presented during the three-day meeting by authors from ten countries. The technical sessions were devoted to: A1 Properties of Ice; A2 Ice Modelling; A3 Ice Experiments and Field Tests; B1 Vessels in Ice; B2 Structures in Ice; C1 Navigation in Ice; C2 Ice Management; C3 Transportation. There was a Film Evening on Tuesday, when the delegates were able to participate in an interesting narrated video presentation by Professor Douglas Tolderlund of the US Coast Guard Academy in New London, Connecticut, dealing with the operation of US Coast Guard Polar class icebreakers in the Arctic and Antarctic regions. There was also a short movie presented by Professor Per Tryde of the Technical University of Denmark on the NIMBUS 7 multichannel microwave radiometer (SMMR) image of the formation of ice in the East Greenland current(1978-9). The delegates then made their way to the MIT Faculty Club for a social evening with drinks, thanks to the arrangements made by Professor J. J. Connor. The delegates had a very enjoyable evening at the Banquet held on 11 June 1986 at the Hyatt Regency Hotel in Cambridge, Massachusetts. The Guest Speaker was Captain Joseph Wubbold, Chief of Ice Operations in the US Coast Guard. The latter part of the final day was devoted to a Panel Session on the theme Arctic L N G - Present Position and Future Prospects. Mr Arthur G. Berndt of the Energy

October 1986 Transportation, New York, acted as the Moderator. Short techno-economic presentations were given by Mr R. D. Goff of Sohio Petroleum Company on Technical and Economic Trends on Offshore Oil and Gas Exploration in the Arctic, by Mr J. K. S. Lob of Gulf Canada Resources, Calgary, on Arctic LNG Production, and by Mr R. Dick of Melville Shipping Limited on Transportation of Arctic LNG. Questions were then taken from the floor and there was a lively discussion. The Conference was closed by Dr T. K. S. Murthy, Conference Director. The post-conference tutorial on 13 June 1986 was devoted to Vessels and Structures in Ice with lectures from Dr Arno Keinonen of AKAC Inc., Calgary, and Professor Ben C. Gerwick of the University of California at Berkeley. From informal talks with delegates, the impression gained was that the Conference was well organised with papers of the right quality from people who matter in the field of ice technology and that the Proceedings were well printed and produced. The Proceedings of the Conference are available in book form with hard cover from Computational Mechanics Publications, Ashurst Lodge, Ashurst, Southampton SO4 2AA, England. The price is $US105.
FEWR6/Lisbon 2-6 June 1986 The Sixth International Conference on Finite Elements in Water Resources has been successfully held in Lisbon last June. The Conference was organised by the Instituto Superior Tecnico and the National Laboratory of Civil Engineering (LNEC) both of Lisbon. The Conference was opened by Professor Arantes de Oliveira who is Undersecretary of State for Research and a well known scientist who has done pioneering work in the field of finite elements and variational methods. Dr Brebbia, on behalf of the International Organising Committee, stressed the importance of the meeting and its international character and the influence that the meetings have had in stimulating advances in computational techniques in water resources. Professor Gray from Notre Dame, also a member of the Permanent Organising Committee, gave the keynote address dealing with Numerical Modelling for Coastal Type Circulation Problems and stressing the problems encountered by many simulations and the correct way of building these mathematical models. Because of the number of papers it was necessary to arrange two parallel sessions: The Tidal-Flow Forum and the Convection-Diffusion Forum. Special workshop sessions were held on computer simulation for shallow water equations and Navier-Stokes type problems. These sessions were a special feature of the meeting and the organisers felt that they could be very successfully carried out in other similar meetings. The Conference owed much of its success to the dedication of its two local organisers, Antonio S~ da Costa and Antonio Melo Baptista. Antonio S~ da Costa in particular uplifted the meeting with his constant enthusiam.

Once again the Conference was successful m bringing together new as well as established researchers in order to maintain its vitality. It stimulated new ideas related to finite elements, in particular those which make the technique more useful as a research and engineering tool. The policy of the Organisivg Committee of holding the Conference in different locations alternating between North America and Europe will continue with the next meeting tentatively scheduled to take place at MIT in 1988. The Permanent Committee however felt that a Conference which is unable to develop and change will inevitably exhaust itself. In order to avoid this and try to attract new researchers and other areas of interest it has been decided to change the title of the meeting to Computational Methods in Water Resources (CMWR) and include other techniques related to finite elements.

International Conference on Computational Methods for Predicting Material Processing Defects 8-11 September 1987 Cachan, France Defects arising in both bulk and sheet forming operations on metals, polymers and composite materials will be considered. Appropriate methods for explaining and avoiding the occurrence of defects leading to fracture, high porosity or strain localisation and undesirable geometrical imperfections and also elastic springback are of major current interest and practical significance. The recent advances in f'mite plasticity and viscoplasticity, damage modelling, bifurcation and instability theory, fracture mechanics and computer numerical techniques offer new tools for the predition of defects. The present Conference aims to focus on these topics and to provide a forum for presentation and exchange of innovative approaches in this field. Contact: Professor M. Predeleanu, Laboratoixe de Mecanique et Technologie; 61, avenue du Pr6sident Wilson, 94230 Cachan, France. 1TTAC's 1st X1 The Computational Mechanics Institute is among the names of the first eleven training organisations registered in the UK by The Information Technology Training Accreditation Council (ITTAC). In making the announcement, Chairman Sir Monty Finniston said: 'There is a large and growing demand overseas for IT training which the UK is well-placed to meet. It is ITTAC's job to see the high standards already established by the British computer and computer service industries are maintained; that the names of the best training establishments are communicated abroad; and that Britain remains the overseas student's Ftrst-choice for IT training.'

BOUNII .. IY ISCME member Professor W. S. Venturini, University of Sao Paulo, Brazil, is co-director with Dr C. A. Brebbia, of next year's BETECH 87, international conference on boundary element technology, to be held in Rio de Janeiro, Brazil, in June. Other members of the organising committee are Dr W. J. Mansur, Professor J. Telles and Professor L. Wrobel, all of COPPE, Federal University of Rio de Janeiro, Brazil. SDRC now has available a new analysis interface for its I-DEAS software system, the BEASY* engineering code now interfaces directly to the I-IDEAS* Supertab program for pre- and post-processing. BEASY, developed by Computational Mechanics (UK), is a general purpose boundary element anlaysis program which is used for the analysis of stress, heat transfer, electrostatics and field problems. It requires only the boundary or surface to be modelled with elements which substantially simplifies model construction and is computationally efficient for problems with large volume-to-surface ratios. Says Martin Neads, European General Manager, 'This interface represents SDRC's response to the need in the engineering analysis community for unbundled MCAE software. The BEASY interface allows users to take advantage of I-DEAS Supertab's extensive pre- and postprocessing capabilities'. * Registered trade marks.
