Numerical study of the axial compression strength for nano-reinforced filament-wound riser considering curing residual stress
https://orcid.org/0000-0002-8098-5924
Highlights The curing residual stress is beneficial for the compression strength of composite risers. The effect of curing process parameters on the compressive strength was not significant. The addition of nano-reinforced particles reduces the curing residual stresses. The performance of the composite riser is enhanced with the increase of nanoparticle content. The addition of nano-reinforced particles affects the failure mode of the composite riser.
Abstract The present study is dedicated to the numerical analysis of progressive failure damage in multiangle nano-reinforced filament wound risers, with due consideration for process-induced residual stresses. Utilizing a multi-model coupling strategy, we introduce an integrated methodology predicated upon the time-varying material characteristics at a macroscopic scale. Initially, the process-induced residual stresses are anticipated via a sequential coupled numerical simulation methodology based on the time-varying attributes of the material. Subsequently, the curing residual stresses serve as the initial stress for the composite wound riser to prognosticate its axial compressive strength, grounded in the progressive damage model. Finally, the multiparametric effects on the strength properties of the composite risers are further investigated to reveal the intrinsic mechanism. The numerical findings evince that curing-induced residual stress retards both fiber and matrix failure while augmenting the axial compressive strength of the composite riser. Furthermore, the escalation in nanoparticle content diminishes the process-induced residual stresses. Additionally, the incorporation of 5 % nanoparticles yields an enhancement in the strength of the composite risers by approximately 16.26 % relative to those devoid of nanoparticles.
