Estimation of stresses in atmospheric ice during aeolian vibration of power transmission lines [PDF]
, 2010 Aeolian vibration in bare and iced cable was simulated using the theory of cable vibration. High frequency vibration creates stresses in the cable and consequently in the ice covering that cable, which may result in ice failure and eventually ice ...

Model-scale tests on the ice-structure interaction process in shallow water
, 2022 A series of model-scale experiments on the ice loading process against a wide, inclined structure in shallow water was conducted in the Aalto Ice Tank. Experiments with three different ice strengths were performed. Based on the results of the experiments,

Detecting Clouds Associated with Jet Engine Ice Crystal Icing [PDF]
Bulletin of the American Meteorological Society, 2019 AbstractIn the past two decades, more than 150 jet engine power-loss and damage events have been attributed to a phenomenon known as ice crystal icing (ICI). Ingestion of large numbers of ice particles into the engine core are thought to be responsible for these events, which typically occur at high altitudes near large convective systems in tropical ...
