Theoretical model of discontinuities behavior in structural steel

The theoretical development of discontinuities behavior model using the complex variable theory by means of the elliptical coordinate system in order to calculate stress in amicrohole in structural steel is discussed. It is shown that discontinuities, observed atmicrometric levels, grow in a fractal...
