A combined approach to integrate experimental and numerical methods in structural integrity is proposed. Fracture tests were conducted on axi-symmetric notched samples of high-strength steel. Fractographic analysis showed the microscopic topographies after failure and allowed the assembly of micro-fracture maps (MFM) covering the whole fracture surface and containing information on the micromechanisms of fracture in the material. Finite element computations gave the distribution of macroscopic variables at the fracture instant in the area covered by the MFM, to correlate the distribution of continuum mechanics variables with the different topographies included in the MFM.
