The internal structure of the umbilical cable is highly complex, and there is significant frictional contact between its components, the interlayer friction affects the mechanical properties of the umbilical cable and is directly related to the accuracy of subsequent hydrodynamic and fatigue analyses. Therefore, it is crucial to obtain precise friction coefficients and investigate their impact on the mechanical properties of the umbilical cable. To investigate the impact of interlayer friction on the mechanical properties of the umbilical cable, experiments were conducted to measure the friction coefficients of the components in contact within the cable. Considering nonlinear material behavior, large geometric deformations, and interlayer contact friction, a three-dimensional finite element model was developed using a multi-level modeling approach for computational analysis. The results of the analysis indicate that friction has a minor effect on the tensile stiffness of the umbilical cable, but a significant effect on its bending stiffness. As the friction coefficient increases, both the tensile and bending stiffness of the umbilical cable correspondingly increase.
