... for cylindrical structures and for conical structures with grounded rubble pile or accreted ice foot. In general, this indentation phenomenon is characterized by the simultaneous occurrence of viscous (rate-dependent) and fracture behavior. Several theoretical models based on approximate methods of analysis...

... appropriate ice-structure interaction conditions. In this paper, following a general review of the basic concepts published by the authors and others in the area of rubble pile formation and force transmittal, extensions of the theory are presented and results are compared with previously published work...

... are photographs taken during the winter of 1980/81 at the Netserk South location, an abandoned island which has eroded to below mean sea level. These photographs show a rapid growth in the size of the rubble field within a period of five days. This rubble pile and other similar ones are formed during periods...

... is also included. Governing loads are taken as the smaller of the impinging ice formation (sheet, ridge, or another rubble pile) limit load and the associated ice pile capacity. The ice formation limit loads are calculated utilizing multimodal theory developed by the senior author previously. Design...
