Structural Failure and Plasticity
Preface
The IMPLAST series of symposiums began in 1973 at the Indian Institute of Technology, in New Delhi, India. The theme of the symposia has been in the large deformation of materials and structures subjected to quasi- static, medium and high rates of loading. This symposium is the seventh in the series and the first time it has been held outside of India. Australia was chosen as a venue because of the strong bond that exists between the two countries and also because of the research work currently being carried out in the field of impact mechanics, crashworthiness and plastic deformation of structures. Delegates from more than 20 different countries from 5
continents have come together to present and discuss results from numerous studies in the field of impact and plasticity. What better place to hold such an international event at the start of the new Millennium than in a
young nation, where a week before the symposium another inspiring international event was held, the Olympic Games.
Most of the symposia have been run under the careful guidance of Professor N. K. Gupta. A very warm and generous host, Professor Gupta always encourages international researchers to visit his institute to motivate and
inspire his fellow researchers. He has also encouraged a large number of famous international researchers to attend and speak at the various IMPLAST symposia so as to enhance the exchange of ideas and results among the world's applied mechanics fraternity. Professor Gupta's keynote lecture provides an overview of the contribution the IMPLAST series has made to impact and plasticity engineering and provides further insights
into the plastic deformation of tubes and frusta.
Melbourne has traditionally had a very strong research school in thin-walled structures. This evolved as a result of investigations into the West Gate bridge failure by the distinguished Professor Noel Murray. His contribution
to engineering was honoured at the symposium dinner. This is also why this symposium had a distinct focus on thin-walled structures by the other two keynote presenters. Professor Rhode's paper provides an excellent overview of buckling of plated and thin walled structures, whereas Professor Usami's paper on plastic
deformation of thin-walled structures under cyclic loading provides us with some valuable information on how such structures behave during seismic events.
As mankind continues to push back the boundaries and begins to explore other worlds and the ocean depths, a thorough understanding of how structures behave when subjected to extremes in temperature, pressure, and high loading rates will be essential. This symposium provides the perfect forum for presenting research into structures subjected to such extreme loads. There were a large number of papers presented under topics of impact, blast and shock loading, indicating a strong research interest in high rates of loading. Similarly new topics have been added to the traditional symposia list such as fire loading, earthquake loading, and fatigue and connection failures. It is clear now that fundamental knowledge of plastic deformation of structures subjected to
various extreme loads is coming of age.
When the planning of this symposium began a large number of distinguished researchers agreed to join the International Scientific Committee to assist with technical content. The editors are honoured and grateful to all the members for their assistance. The editors were also saddened by the recent passing away of Dr. Raymond Woodward from Australia and Dr. Dusan Kecman from Cranfield, IYK. The international applied mechanics community holds Dr. Woodward's contributions to understanding material behaviour subjected to impact loads
and in particular penetration mechanics, and Dr. Kecman's contributions to crashworthiness standards for vehicles and in particular bus rollovers, in high regard. As quiet achievers who encouraged scientific endeavour,
their contributions and company will be sadly missed.
The editors would also like to thank the organising committee for their assistance. They would also like to thank in particular the reviewers of the papers listed in the proceedings. Each full paper was peer reviewed by at least two experts in the field. The editors are most grateful to them for giving up their valuable time. Finally the
editors would also like to warmly thank each of the delegates for preparing their papers, attending the conference and helping make the IMPLAST series a success.
