An investigation of the crack propagation in tool steel X38CrMoV5(AISI H11) in SET specimens

Abstract : An approach is proposed for the evaluation of surface fatigue damage of hot forming tools that undergo severe thermo mechanical loading. Fatigue crack propagation in a hot work tool steel X38CrMoV5-47HRC is investigated using single-edge cracked tension specimens with 3 different thicknesses (2.5, 1, 0.6 mm) and two R-values. The stress intensity factor is evaluated with ABAQUS®. Paris curves are established for the crack propagation experiments.
