51317--9656-Marine Structural Integrity Subject to Mechano-Electrochemical Induced Corrosion

Picture for Marine Structural Integrity Subject to Mechano-Electrochemical Induced Corrosion
Available for download

An experimental protocol including in situ potentiostat and quasi-static tensile tests to provide an improved understanding of the corrosion behavior of UNS G10210 steel. A local-global finite element method has been proposed to model a steel plate at a ship compartment scale under uniaxial quasi-static tensile/compressive loading.

Marine structural integrity subject to mechano-electrochemical induced corrosionY. Wang(12*) J.A. Wharton(2) J. Downes(1) R.A. Shenoi(1)(1) Fluid Structure Interactions Research Group Engineering and the Environment Boldrewood Innovation Campus University of Southampton Burgess Rd UK SO16 7QF(2) National Centre of Advanced Tribology at Southampton Engineering and the Environment Highfield Campus University of Southampton Southampton UK SO17 1BJ*Email: yw4u14@soton.ac.ukAbstractCarbon steel marine platforms including ships and offshore structures are at high risk of corrosion due to the combination of aggressive seawater environment corrosive cargoes and constantly changing loading conditions. In particular the combined influence of mechanical and electrochemical effects (which is often termed mechano-electrochemistry) has gained increasing attention over the last decade. Although various experiments along with theoretical/empirical expressions have been proposed to establish the relationship between stress/strain and the corrosion behaviour there are few in situ measurements of corrosion and the mechanical properties. Moreover such corrosion mechanisms have not been incorporated for large scale ship or offshore structural members. This work has developed an experimental protocol includingin situ potentiostat quasi-static tensile tests and the scanning Kelvin probe measurements to provide an improved understanding of the corrosion behaviour of AISI1020 steel at different stress levels. A novel local-global finite element method has been proposed to model a steel plate at a ship compartment scale under uniaxial quasi-static tensile/compressive loading. The stress distributions together with the experimental measurements were utilised to simulate a local time-dependent mechano-electrochemical corrosion process from which the changed structural topography was inserted back to the global model to provide the updated stress/strain level and the ultimate collapse strength. The modelling results demonstrate a more realistic approach to estimate marine structural integrity considering stress-induced localised corrosion.Keywords: carbon steel; marine corroion; quasi-static loading; scanning Kelvin probe; finite element method.
