In this work,a finite element model was developed to study mechano electrochemical effect of pipeline corrosion through a multiphysics field coupling technique.The modeling results,i.e.,corrosion potential and corrosion current density,are well consistent with experimental measurements on pipeline steel in anear-neutral pH solution.It is demonstrated that,while a tensile strain enhances stress uniform ly through pipe wall,an increasing dep th of corrosion defect results in a concentrated stress at the defect center only.When the corrosion defect is under an elastic deformation,there is no apparent effect of mechanical–electro chemical interaction on corrosion.However,when the applied tensile strain or the geometry of corrosion defect is sufficientto cause a plastic deformation at the defect,the local corrosion activity is increased remarkably. Corrosion at the defect is composed of aseries of local galvanic cells,where the region with ahigher stress,such as the defect bottom,serves as anode,and that under lower stress,such as the defect sides,as cathode.The locally accelerated corrosion at the defect center can be further enhanced as the corrosion defect deepens.
