Efforts to implement continuum damage models in forming simulations are hampered by the absence of experimental techniques to provide reliable and accurate damage-evolution parameters. The widely used indentation approach, whereby deformation-induced damage is quantified through the degradation of indentation hardness and modulus, was shown to be intrinsically deficient (Tasan et al. [18]). Here,...
This paper scrutinizes the reliability of indentation-based damage quantification, frequently used by many industrial and academic researchers. In this methodology, damage evolution parameters for continuum damage models are experimentally measured by probing the deformation-induced degradation of either hardness or indentation modulus. In this critical assessment the damage evolution in different...
