Discrete Element Analysis of Ice-Induced Vibrations of Offshore Wind Turbines in Level Ice
Journal of Marine Science and Engineering, 2023 Self-excited vibrations of offshore structures interacting with sea ice, characterized by low frequency and high amplitudes, pose significant hazards to offshore wind turbines (OWTs) in cold seas. This study employs the discrete element method (DEM) with

The brittle/ductile transition in cubic stabilised zirconia
Journal of the European Ceramic Society, 1994 Abstract Cubic zirconia has a smooth brittle/ductile transition above 800°C at a loading rate of 1·2 × 10 −4 MPa m s −1 . Pre-stressing at 950°C increases the room temperature fracture toughness in a controllable manner. The toughness increase is caused by dislocation shielding of the crack tip and may be predicted using a model ...
