Photoplastic Effect on Ice
Published online by Cambridge University Press: 16 February 2011
Abstract
The study of the photoplastic effect (PPE) on ice is essential for both fundamental and applied reasons. It is important for an understanding of dislocation motion as well as the flow of glaciers in cold regions that occurs under intensive solar radiation. It was found that the illumination of ice with UV light (λ < 300 nm) leads to its irreversible hardening1. A prolonged irradiation with a total light exposure of about 8.10−5 J/cm2 at λ= 260 nm can change the creep rate up to 60 percent. Even more pronounced PPE was found in HCI-doped ice with the concentration, n= 1018 cm−3. It is suggested that PPE is caused by the excitation of “autoionization” reaction which was found responsible for the photoconductivity of ice.
