IUTAM-IAHR Symposium on Ice-Structure Interaction Professor Bez Tabarrok, Chairman of the Canadian National Committee (CNC) of the International Union of Theoretical and Applied Mechanics (IUTAM) invited Professor Derek Muggeridge to organize a symposium on ice structure interaction. Dr. Muggeridge readily agreed and prepared a proposal that was endorsed by the CNC and presented to the General Assembly Meeting of IUTAM for their consideration. This Assembly gave its approval and provided the local organizing committee with the names of individuals who were willing to serve on the Scientific Committee. Dr. Muggeridge became chairman of this committee and Dr. Ian Jordaan became co-chairman of this committee as well as chairman of the local organizing committee. The symposium followed the very successful previous meeting, chaired by Professor P. Tryde in Copenhagen, by ten years. Both symposia uti lized Springer-Verlag to publish their proceedings. The Faculty of En gineering and Applied Science at Memorial University of Newfoundland were particul{lXly pleased to host this prestigious symposium as it marked the twentieth anniversary of its Ocean Engineering Research Centre.

Although ice-induced vibrations (IIV) resulting from dynamic ice-structure interaction have been reported as infrequent occurrences in nature, the catastrophic consequences of these events makes them a fundamental design consideration for structures in ice-prone regions. Over the last 50 years, these events have affected a wide range of structures, including bottom founded lighthouses, channel markers, jacket and caisson retained structures, and have led to operational shutdowns, human discomfort, and even complete collapse of the structure in some cases. Rigorous experimental investigations and theoretical modeling approaches over the years have provided valuable insight into the physical mechanism of the process; however, a significant amount of uncertainty in identifying the conditions associated with IIV and its severity still exists. The primary source of the uncertainty comes from the complexity of the ice failure process, since it is highly influenced by the interplay of different competing mechanisms, such as fracture, damage and microstructural changes. One of the fundamental components of compressive ice failure is the development of 'high-pressure zones (hpzs),' which are responsible for transmitting the majority of the loads in ice-structure interactions. As the properties and dynamic behaviour of hpzs exhibit similar characteristics over a wide range of scales, efforts to link hpz mechanics with the occurrence of dynamic ice-structure interactions is seen as a promising approach. During ice-structure interaction, the ice failure process is highly influenced by different interaction parameters. An uncertainty analysis with self-excited vibration modeling approaches was performed first to identify the critical parameters and how their effects can propagate through the dynamic ice-structure interaction process. Based on the simulations, ice temperature, interaction speed, and interaction area were identified as the key parameters affecting the dynamic ice-structure interaction process. A medium-scale ice crushing dynamics test program was then carried out to study the influence of these parameters on the dynamics of hpzs under controlled conditions with variable structural compliance. In general, more severe dynamics associated with failure behaviour were observed to be more pronounced for colder ice, smaller interaction areas, higher interaction speed, and lower structural compliances. The observed dynamics of a single hpz was then used to develop a simplified ice-structure interaction model. The behaviour of the hpz was estimated using results from previous triaxial tests, which showed a non-linear relationship between hpz stiffness and the nominal strain, with the degree of softening depending on the average strain-rate. Two distinct failure processes were assessed in the context of the periodic sinusoidal response of the structure using the model. First, such responses can result from the vibration within the layer of damaged ice when the formation of the damaged layer and the extrusion process become cyclical in pure crushing. Theoretical calculation from a previous study was adopted to estimate the equilibrium layer thickness that can result in such vibrations, and the model showed reasonably good agreement with the calculations. The other failure process considered was for spall-dominated interactions with occasional crushing events. Such a failure process can result in frequency lock-in of the structure; however, these responses were observed to be highly sensitive to interaction speed and structural parameters. This was identified as the primary reason for the infrequent observation of frequency lock-in in full-scale interactions. Although the simplified modeling framework presented here shows promising results, further experimental investigation and modeling refinement are required for a full-scale implementation.

New edition of the leading resource on the Arctic and Southern Oceans with contributions from the world’s experts on sea ice Sea Ice delivers insights into the very latest understanding of sea ice dynamics, how we measure (and model) its extent, the ecosystems that depend on sea ice, and the effect of climate change on its distribution. The book also discusses how sea ice influences the oceanography of underlying waters and the influence that sea ice has on the world’s climate. This newly revised and updated Fourth Edition looks at ice-based food webs and the impact on global geopolitics as well as changes in human activity in the Arctic. Written by a team of more than 80 of the world’s leading experts from 13 countries, Sea Ice includes information on: Sea ice thickness distribution and snow and surface processes on sea ice The short-term and long-term dynamics of Arctic versus Antarctic Sea ice Current methods of satellite remote sensing of sea ice The ecology of sea ice, from microbes to mammals to marine birds The cycling of contaminants across the ocean-sea ice-atmosphere interface In its new edition, Sea Ice remains the leading multidisciplinary resource on the subject for all policy makers, researchers, and students with an interest in the polar regions and their role in the world’s oceanic systems.
