The deformations and stresses in floating ice plates

Acta Mechanica, 1972
In the past, the analyses of floating ice plates subjected to static or dynamic loads were based on the theory of a thin homogeneous plate, although in actual floating ice plates Young's modulus may vary strongly with depth. Recently,A. Assur concluded, on the basis of a heuristic argument, that the solutions obtained for homogeneous plates may be used

Light scattering by horizontally oriented ice crystal plates

Journal of Quantitative Spectroscopy and Radiative Transfer, 2007
Abstract Phase functions for hexagonal ice plates randomly oriented in the horizontal plane are calculated with a facet-tracing code. The bright optical phenomena like sundog and parhelion 120 ∘ are quantified by their weight coefficients that are tabulated as functions of both incident angles and particle aspect ratios.

Time dependent deflections of nonhomogeneous ice plates

Acta Mechanica, 1976
Two characteristics of floating ice plates which are important in engineering problems are the effect of temperature on the mechanical properties of ice, and the viscoelastic response of ice under prolonged loading. In this paper, the floating ice plate is considered as a viscoelastic plate on an elastic foundation.

Moving loads on ice plates of finite thickness

Journal of Fluid Mechanics, 1991
The response of a floating ice plate to a moving load is given in terms of a pair of Green's functions. General expressions for these Green's functions are derived for the case of an infinite isotropic plate of uniform thickness supported on a fluid base of uniform depth.

Numerical simulations for plates under ice impact based on a concrete constitutive ice model

International Journal of Impact Engineering, 2020
Abstract Polar ships and offshore platforms frequently experience floating ice impacts or iceberg collisions in Arctic region, which may cause permanent deformations of plates, resulting in negative effects on their work performance. The modeling of ice material is critical and difficult point to study the ice-structure interaction.

Surface Ice Detection on Composite Plates with Ultrasonic Guided Waves

2019 IEEE 5th International Workshop on Metrology for AeroSpace (MetroAeroSpace), 2019
The paper presents an integrated active system for ice detection on composite plates with ultrasonic guided waves. The aim is to efficiently detect ice formation and growing on complex structures to ensure safety in transportation vehicles. Ice may lead to serious hazards and its early detection is crucial to avoid catastrophic events.

Lidar Backscatter from Horizontal Ice Crystal Plates

Journal of Applied Meteorology, 1978
Abstract Some unusual lidar returns from an altostratus cloud are interpreted in terms of reflections from hexagonal ice plates falling with their long axes aligned in the horizontal. Such an explanation is consistent with the observed high backscatter coefficients and low depolarization ratios and also with the temperature range (−12 to −20°C) of the ...

Simulations of Ice Nucleation by Model AgI Disks and Plates

The Journal of Physical Chemistry B, 2016
Silver iodide is one of the most effective ice nuclei known. We use molecular dynamics simulations to investigate ice nucleation by AgI disks and plates with radii ranging from 1.15 to 2.99 nm. It is shown that disks and plates in this size range are effective ice nuclei, nucleating bulk ice at temperatures as warm as 14 K below the equilibrium ...

Cooling architectures using thermal sidewalls, interchip plates, and bottom plate for 3D ICs

2017 18th International Symposium on Quality Electronic Design (ISQED), 2017
Thermal management for three-dimensional integrated circuits (3D ICs) is becoming a crucial challenge. In this paper, we propose new cooling architectures using thermal sidewalls, interchip plates, and a bottom plate (thermal-SIB architectures) for 3D systems that have a power dissipation of several tens to a couple of hundred W/cm2 as a vertical ...

The Influence Surface Method for Floating Ice Plates

Canadian Geotechnical Journal, 1975
In order to simplify the calculations of bending moments in floating ice plates subjected to slowly moving loads or static loads of short duration, influence functions for infinite plates floating on a liquid are derived and then presented graphically in the form of influence charts. The presented charts and analyses are based on the elastic theory of
