Abstract
A method is developed to evaluate the surface fatigue damage of hot forming tools (forging, HPDC) that undergo thermo mechanical loading and environmental attack. Crack propagation under fatigue loading in a hot work tool steel X38CrMoV5-47HRC is investigated using SENT (single edge notched tension) specimens of 2.5*8 mm*mm section. The effect of different testing conditions has been investigated: effect of thickness (ranging from 2.5mm – 0.10mm), effect of R value and effect of temperature are observed on crack propagation properties of the steel. Paris curves are established. Numerical simulation is performed by ABAQUS® Standard to evaluate J integral and stress intensity factor KI. A new crack driving force parameter is introduced. Mechanisms of crack propagation have been studied under different test conditions.
