... environments (Seidel, 2024). Experimental investigations involve EN 14399-4 bolting assemblies under varying lubrication conditions and salt contents, revealing that water adversely affects the friction coefficients, particularly with MoS 2 lubrication. Conversely, variations in salt content appear less...

..., it is essential to assess whether the product can withstand high loads applied by the tensioner pads without causing damage to the outer sheath, filter, or core fibers. Additionally, it is crucial to verify that the internal friction coefficient of the product aligns with the assumed value used to establish...

... ice temperature and contact pressure certain correlations were obtained. For deformed ice (a consolidated hummock layer was studied), the friction coefficient in the case of concrete is about 15% higher than of level ice. It was shown that the friction coefficient remained constant throughout...
