WitrynaThe undrained cyclic shear strength has to be evaluated to calculate the capacity under cyclic loads. The undrained cyclic shear strength should be obtained for various stress paths. The remolded shear strength is an important parameter because it is used to calculate the penetration resistance of the skirt walls. WitrynaThere are two primary benefits of reducing ice adhesion: •. IPS requiring lower energy could be used; •. the removal of ice is cleaner. Early studies in the aeronautic field on static ice adhesion to surfaces ended up with the following conclusions: •. adhesive shear stress increases linearly with decreasing surface temperature; •.
