Backscattering peak of hexagonal ice columns and plates

Optics Letters, 2000
The backward cross section of hexagonal ice crystals of arbitrary orientation is calculated for visible light by means of a ray-tracing code. It is shown that backscattering of the tilted crystals is caused by a corner-reflector-like effect. A very large peak of backscattering is found for a tilt of 32.5 degrees between the principal particle axis and ...

Structure and Properties of Ice Plates

1996
In order to make any problem tractable, the applied mathematician must make some assumptions about nature. It is an aim of this chapter to introduce the reader to the physical and mechanical properties of ice sheets, so that they may judge for themselves the validity of the assumptions made throughout the remainder of the book.

Time Deflection Behaviour of Ice Plates

1986
In analyzing ice plates it has been customary to use rather simple material models. In this paper a theory for viscoelastic plates is presented which uses a more realistic nonlinear constitutive law for ice, incorporating the most recent experimental data and including all three stages of creep and hereditary effects.

Advanced plating photoresist development for advanced IC packages

2015 16th International Conference on Electronic Packaging Technology (ICEPT), 2015
The advanced IC packaging technologies such as 3D-TSV, 2.5D interposer, PoP and Flip-Chip wafer micro-bumping are being implemented for consumer electronic products like as mobile phones, tablets, and so on. The form factor of consumer product trends toward small and thin which driving IC packaging toward smaller, thinner and more complicated.

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.
