Abstract

Abstract

Marine composite pipes and cables are critical connection structures in offshore energy development. They are typically composed of metallic reinforcement layers, polymer sheaths, functional units, and interfacial layers, and are characterized by multilayer composite configurations, heterogeneous material combinations, and slender flexible geometries. Under the combined effects of complex marine environments and loading conditions, including waves and currents, internal pressure, temperature, floater motions, and seabed constraints, these structures exhibit pronounced material nonlinearity, geometric nonlinearity, interfacial nonlinearity, and contact nonlinearity, which directly affect their structural analysis, strength assessment, and service safety. Focusing on the research progress on nonlinear problems in marine composite pipes and cables, this paper systematically introduces their multilayer composite structural characteristics and the underlying causes of nonlinearity. It reviews the constitutive theories associated with material nonlinearity, including the hyperelastic and viscoelastic behavior of rubber and polymer materials, as well as the elastoplastic constitutive models of metallic materials. The major modeling approaches for geometric nonlinearity, including slender-rod theory, the lumped-mass method, the co-rotational method, and the absolute nodal coordinate formulation, together with the corresponding solution strategies, are comparatively reviewed. The theoretical developments related to interfacial nonlinearity, including interfacial strength, interfacial friction, and interfacial fatigue nonlinearity, are summarized. In addition, the classical theories and improved models for pipe/cable–seabed interaction in contact nonlinearity are discussed. Although substantial progress has been made in existing studies, the understanding of the coupled mechanisms of multiple nonlinearities under complex marine environments remains insufficient. Future research should therefore focus on coupled analyses of multiple nonlinear behaviors under multiphysics, multiscale, and long-term service conditions, so as to provide more reliable theoretical support for the safe design and long-term integrity assessment of marine composite pipes and cables.
