Abstract

PurposeValidate the resistance of bolted connections in terms of stresses, resistant moment and contact pressure.Design/methodology/approachFinite element modeling of corroded bolted joint.FindingsThe three types of corroded assemblies are resistant to the applied loads.Originality/valueThe research is original, it studies the stress corrosion cracking of a bolted assembly's end plate by the finite element method.

FE modeling of the effect of conductivity in galvanic corrosion between different types of stainless steel and carbon steel in a structure bolted joint

“…The risk of galvanic corrosion often justifies a warning against combinations of dissimilar metals in corrosive environments. The corrosion is stimulated by the potential difference that exists between the two metals, the more noble acting as a cathode where some oxidizing species is reduced, the more active metal, which corrodes, acting as the anode (Radouani et al, 2017(Radouani et al, , 2021). The corrosion rates (CRs) and the potential distribution over a galvanic couple depend upon the electrochemical properties of the metals, on environmental variables such as temperature, salinity, oxygen content and solution flow, as well as the geometry of the corroding system.…”
