Head-on collision between two hydroelastic solitary waves with Plotnikov-Toland's plate model
Theoretical and Applied Mechanics Letters, 2018 : Head-on collision between two hydroelastic solitary waves propagating at the surface of an incompressible and ideal fluid covered by a thin ice sheet is analytically studied by means of a singular perturbation method.

Blasim: A computational tool to assess ice impact damage on engine blades [PDF]
A portable computer called BLASIM was developed at NASA LeRC to assess ice impact damage on aircraft engine blades. In addition to ice impact analyses, the code also contains static, dynamic, resonance margin, and supersonic flutter analysis capabilities.

Combined effect of ice cover and length-to-diameter ratio on the wave resistance of a slender body
Applied Ocean ResearchIn this study we considered the rectilinear motion of a slender body in fluid under an ice cover. The liquid is inviscid and incompressible. The ice cover was modeled as a floating viscoelastic plate, and the slender body was modeled as a source–sink ...

Performance of Ice Slurry Generator with Mechanical Scraper using R-22 and R-290
International Journal of Technology, 2017 Ice slurry technology is highly favored to maintain the freshness of fish, as the cooling capacity of ice slurry is higher than that of flaked ice, tubular ice, plate ice, and block ice. One important part of an ice-slurry system is the ice generator.

Experimental Investigation of Sublimation of Ice at Subsonic and Supersonic Speeds and Its Relation to Heat Transfer [PDF]
An experimental investigation was conducted in a 3.84- by 10-inch tunnel to determine the mass transfer by sublimation, heat transfer, and skin friction for an iced surface on a flat plate for Mach numbers of 0.4, 0.6, and 0.8 and pressure altitudes to ...

Sea Ice Crack Characteristics and Ductile–Brittle Transition Mechanism Under Low Velocity Impact
Journal of Marine Science and EngineeringDrop hammer impact tests were conducted to study crack features and the ductile–brittle transition in sea ice under low-speed impact. Crack images were analyzed using Hessian filtering and Hough transform methods, and a finite element model was created ...

On the Buckling Force of Floating Ice Plates [PDF]
, 1980 The calculation of the largest horizontal force a relatively thin floating ice plate may exert on a structure requires the knowledge of the buckling load for this floating plate. In the published literature on the stability of continuously supported beams and plates it is usually assumed that this buckling force corresponds to the lowest bifurcation ...
