“…3. Moreover, in the thermography experiments conducted in the companion paper [6], it was seen that cracks grow during loading. The numerical simulations show that for larger maximum indenta tion forces, the stress field indeed encourages crack growth during loading, but not for smaller maximum indentation loads [6] where interfacial tensile stresses appear during unloading.…”

“…However, as was shown in our previous work, the results may be hard to interpret since they are indirectly asso ciated with material toughness (not just interfacial toughness) and deformation modes, and may even give contradicting results [6,7]. In our experimental work, we investigated Rockwell indenta tion of thermal barrier coatings, where the indentation was con ducted on the surface of a thermal barrier system so to establish the interfacial fracture toughness [6].…”
