Dynamic Response of Overhead Transmission Lines with Eccentric Ice Deposits Following Shock Loads [link]Paper  abstract   bibtex   
Two types of ice failure criteria are modified and combined to model the shedding phenomenon of eccentric ice deposits on overhead power transmission lines impacted by shock loads. The criteria are formulated in a user-defined element rupture subroutine, and implemented into nonlinear finite-element (FE) analysis using commercial software. The proposed modeling method is validated by the comparison of results from a physical deicing test on a real-scale 100 m single-span line and those obtained from numerical simulation. The FE model proves to be capable of differentiating eccentric ice from concentric ice deposits and confirms the ice shedding response observed in tests. The improved modeling method can be used for the design and evaluation of transmission lines in cold regions, and for the design and optimization of mechanical deicing devices and methods.
