Researchers in the field of fracture mechanics, today predominantly developing appropriate
solution algorithms for problems of solid bodies with cracks. Problems in mechanics
generally, related with fracture and fatigue for solid bodies with various geometries of sharp
notches, are studied to a much lesser extent. This situation can be explained by analytical
difficulties 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 rounded
notch tip with a significant radius of curvature, simplified solutions with are therefore of
great importance. Recent years, due to constant rise of computing power and development of
numerical methods, re-evaluation of stress concentration factors from a viewpoint of theory
of elasticity is present. This is mainly as a feedback from industry which have requirements
toward mega and nanostructures.Corrosion represents an important limitati...on to the safe and
reliable use of many alloys in various industries. Pitting corrosion is a form of serious
damage on metals surface such as high-strength aluminum alloys and stainless steel, which
are 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 is
application of new method of determine length scale parameter for estimating the
mechanistic aspect of corrosion pit under uniaxial/multiaxial high-cycle fatigue loading.
