High pressure zones at different scales during ice-structure indentation
In order to improve the estimation of the ice load during ice-structure interaction, this study aims to investigate the behaviour of high pressure zones at different scales. Small scale indentation tests of ice with four different sizes of indentors (10 mm, 20 mm, 40 mm and 100 mm in diameter) were...
