Application of gradient elasticity on corrosion fatigue damage assessment
Апстракт
Researchers in the field of fracture mechanics, today predominantly developing appropriatesolution algorithms for problems of solid bodies with cracks. Problems in mechanicsgenerally, related with fracture and fatigue for solid bodies with various geometries of sharpnotches, are studied to a much lesser extent. This situation can be explained by analyticaldifficulties arising in solving problems of elasticity theory for bodies with rounded notches.To solve problems of such class, starting from data on stress concentration in the roundednotch tip with a significant radius of curvature, simplified solutions with are therefore ofgreat importance. Recent years, due to constant rise of computing power and development ofnumerical methods, re-evaluation of stress concentration factors from a viewpoint of theoryof elasticity is present. This is mainly as a feedback from industry which have requirementstoward mega and nanostructures.Corrosion represents an important limitation to the safe andre...liable use of many alloys in various industries. Pitting corrosion is a form of seriousdamage on metals surface such as high-strength aluminum alloys and stainless steel, whichare susceptible to pitting when exposed to a corrosive attack in aggressive environments.This is particularly valid for dynamic loaded structures. The subject of this paper isapplication of new method of determine length scale parameter for estimating themechanistic aspect of corrosion pit under uniaxial/multiaxial high-cycle fatigue loading.
