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 ...
