Approximation of the crack-tip field in fatigue cracks in bridge steel specimens: DIC analysis of different constraint levels

A study on the accuracy of the approximation of the displacement field around of crack tip in a sample made from bridge steel (S355) is main objective of contribution. Linear elastic fracture mechanics (LEFM) theory in framework of multi-parameter formulation, i.e. postulated by Williams is used to...
