 The harsh conditions of submarines pose a major challenge to the longevity of offshore wind farms. To address this issue, researchers have developed numerical simulations to study how pores in the insulation material can expand and merge due to the intense electric field generated by high-voltage wires. This phenomenon, known as water-treeing, can lead to plasticization near the pores, which could cause them to coalesce and ultimately lead to failure of the insulation material. The researchers also investigated the influence of various factors such as the distance between voids, the relative size of voids, and the shape of voids on the rate of coalescence. Finally, they simulated a generic microstructure with randomly distributed voids under an electric field. This article was authored by Michel Macelli, Walter Carvelli, and Monsef Drissihafti.
