On the elasticity of ice plates
Canadian Journal of Civil Engineering, 1988 The rigidity modulus is determined for simply supported, circular ice plates 0.5 and 1.22 m in diameter. Measurements for the 0.5 m diameter plates were made at −10 °C and for the 1.22 m plates in the range of −7 to −37 °C. The elastic moduli and Poisson's ratio, calculated from the rigidity modulus, are in the range of 6.0–12.0 GPa and 0.29–0.60 ...

Constraining the parameter space of comet simulation experiments [PDF]
, 2018 Our interpretation of the data returned by Rosetta and other cometary missions is based on the predictions of theoretical models and the results of laboratory experiments. For example, Kossacki et al. (2015) showed that 67P's surface hardness reported by

An experimental apparatus for observing deterministic structure formation in plate-on-pedestal ice crystal growth [PDF]
, 2015 We describe an experimental apparatus for making detailed morphological observations of the growth of isolated plate-like ice crystals from water vapor. Each crystal develops a plate-on-pedestal (POP) geometry, in which a large, thin, plate-like crystal ...

Treatment of ice-shelf evolution combining flow and flexure
Journal of Glaciology, 2021 We develop a two-dimensional, plan-view formulation of ice-shelf flow and viscoelastic ice-shelf flexure. This formulation combines, for the first time, the shallow-shelf approximation for horizontal ice-shelf flow (and shallow-stream approximation for ...

CRACK FORMATION IN ICE PLATES BY THERMAL SHOCK
Canadian Journal of Physics, 1963 Cracks were formed in the surface of smooth ice blocks by bringing them into contact with a second colder ice block. The temperature change within each block and the associated thermal stress were calculated. The ultimate strength of a smooth ice surface was found to be between 30 and 40 kg/cm2.

Motion of a submerged body in a near-surface water environment
International Journal of Naval Architecture and Ocean Engineering, 2022 This study considered the motion of a submerged body near the free surface of a liquid and a liquid covered with ice cover, both theoretically and experimentally. Mathematically, the body was modelled using the source–sink system.

The scattering of waves by an elastic floating body on water of variable depth : a thesis presented in partial fulfillment of the requirement for the degree of Master of Science in the subject of Mathematics at Massey University, Albany, New Zealand [PDF]
, 2000 For many years polar scientists and offshore engineers have studied the behavior of a floating body in the presence of ocean waves. A large floating structure, such as a floating runway or an ice sheet, is sufficiently thin so that elasticity is ...
