Sharaf et al [28] conducted an experimental and numerical analysis of the behavior of corroded steel plates strengthened with thin-ply glass/carbon hybrid FRP composites. The combined flexural and bearing strength of rehabilitated corroded steel circular hollow sections (CHS) under quasi-static large deformation three-point bending and direct indentation using CFRP sheets have been tested by Elchalakani et al [29,30].…”

The purpose of this study is to investigate the stress concentration of a corroded steel plate strengthened with carbon fiber reinforced polymer (CFRP) plates. An accelerated corrosion experiment was first executed to acquire corroded steel plates, and then surface profile measurements were conducted to obtain 3D coordinate data of the corroded steel surface. Finite element models considering the surface morphology of the corroded steel plate and the interfacial bonding properties between the CFRP plate and the corroded steel plate were established to investigate the stress concentration of the corroded steel plate strengthened with and without CFRP plates. The reliability of the numerical modeling method was verified based on a mesh convergence analysis and a comparison of the fatigue test, 3D morphology scanning, and numerical analysis results. Specimens with five levels of corrosion damage, six kinds of CFRP-strengthening stiffness, five kinds of adhesive thickness, and five levels of CFRP prestress were numerically modeled. The primary indications consist of features of stress distribution, and the stress concentration factors Kt and Ktg were analyzed. Results showed that the features of stress distribution and the stress concentration factor Kt of the corroded steel plate strengthened with and without CFRP plates are only related to the shape, size, and position of rust pits, but not to the degree of uniform corrosion or the reinforcement parameters. The value of Kt for the corroded steel plate with a corrosion duration of 6~18 months and a weight loss rate of 9.16~21.78% was approximately 1.199~1.345. The converted stress concentration factor Ktg has more practical significance than the stress concentration factor Kt in describing the influence of corrosion and CFRP reinforcement on the peak tensile stress of the corroded steel plate. The value of Ktg increased linearly with the increase of the weight loss rate of the corroded steel plate and decreased appreciably with the increase of the strengthening stiffness and prestress level of the CFRP plates, and it presented a very small increasing trend with the increase of the adhesive thickness.

“…Experimental [1][2][3], numerical [4][5][6] and analytical [7-9] study of CFRP-repaired steel plates were conducted in recent years. Mohabeddine et al [10] proposed an analytical model to predict type I fatigue crack extension in steel central cracked tensile specimens with carbon fiber reinforced polymer (CFRP) bonded on both sides of the steel plate.…”

The crack repair and transformation of port machinery has gradually become a hot-spot research. In this paper, a numerical analysis of tensile performance of central cracked steel plates repaired with CFRP sheets was conducted. The effect of the reinforcement method, the radius of the hole, the length of the fatigue crack and the size of the patch on the repair effect of the steel structure was investigated. The effect of repair was measured by the stressstrain state, load-displacement curve, and stress intensity factor. The results showed that the residual strength of the steel structure was significantly improved after the repair of CFPR materials, and a more reasonable patch size was given. The obtained results provided important methodological and data support for guiding the repairing work.
